Full Native tank

Recommended Posts

Well the tank I call my "Native Tank" is now I think officially full. The little spotted blue eyes have been doing their thing and I recently just spied another 2 newborn fry and a slightly older one. I am hoping to eventually end up  with a really decent sized self maintaining school of them. Sharing the tank are Blackmore River Shrimp which seem to go through phases of heaps and lots of babies down to a few, back up to a population explosion as it warms up again. The tank is heated of course other wise they would freeze in winter, but they still seem to decline or slow in breeding during winter.

Then there are the Northern Australian Chameleon Shrimp also in the tank, I don't often get to see them but when I do they are always a pleasure. The tank is now also home to a group of Darwin Algae Shrimp, and most recently some Darwin Red Nose Shrimp. In all honesty I think instead of simply calling this tank my native tank I need to call it my NT tank.

But then there is the snails that are sharing the tank with all the NT beauties. Slowly but steadily I have increased the notopala snails up to now 8 which has taken many hours of regular searching in a local stretch of river watching all the time for crocs. With the notopala snails I have also found some other gems, namely a HUGE type of long black snail along the lines of MTS, but these black ones are a LOT bigger and have pretty yellow spots on their bodies. The other snail of interest is a smaller snail again similar in shape to MTS and roughly around the same size but it has very defined blunt spikes on its rather chunky shell.

@Baccus, this is flaping awesome man, love native tanks, more photos please, have you considered a group of Threadfin Rainbows? How large is the tank? Have you noticed at all that Darwin Red Nose Shrimp eat plant life? Where abouts did you get the native snails from? North Australian Chameleon Shrimp are great aren't they, a seriously under rated Shrimp, actually my favourite of all Shrimp that are on offer to keep, Darwin Algae Shrimp are pretty cool also, what are the plants you have in there? Natives also? More photos man, more photos!

ARGH! I wanna do another native tank!

Thanks for the encouragement !

I do have some threadfin rainbows but they are in the 4ft tank, this NT tank is only 61 x 30 x 38 cm. The log in the tank pretty much dominates the tank. The spotted blue eyes where mainly only in the tank as mosquito control, but I am also quite taken by them in their own right and so far they and the shrimp seem to co-habit very comfortably. Pacific Blue eyes I know would have made a meal of these much smaller native shrimp, where as Cherry shrimp seem to be able to out breed any predation by the pacific blue eyes.

Plant wise they pretty much are native aside from the java fern that hitched a ride somewhere along the line and has attached itself to the log. In the tank there is thin leafed Val, Hornwort (from the NT) and I think Rotala Mexicana (also from the NT) and probably an introduced plant that I have always known as parrots feather (but that could be the wrong name).

The hornwort grows like crazy so if the rednoses and DAS want to eat it by the bucket load it saves me having to throw it out all the time. I always hate having to throw away weed since I know the blue eyes have often laid eggs in it. Plus the jungle tangle helps the fry and shrimplets survive and find food.

The native snails have all come from the Fitzroy River in Rockhampton, I have looked in some other local creeks for snails but so far have not come across any as interesting as from the Fitzroy. Apart from this next snail that I am having trouble identifying.

The above snail has not separate mouth part like the notopalas, nor does it have the trapdoor flap that the notopalas and some other snails have. Since putting some other new plants in the tank with it, the snail has taken to hanging around the new plants (I don't think its eating it so far just cleaning it) where as it ignored totally the existing plants all ready in the tank.

Just for you some more notopala species

Nice photos! Man I love NA Chameleon Shrimp, is this tank outside? I ask because you said about the Blue Eyes for Mozzie control, check out those spiky shelled snails, look mad hey!

The Parrots Feather is I think called  Myrio (Myriophyllum aquaticum), grows like crazy doesn't it.

The tanks are in the car shed, with open tops so the mozzies are always laying eggs in the tanks much to all the different fishes enjoyment.

The parrots feather certainly does grow long, between it and the hornwort the tanks tend to fill quickly with plant life.

The spiky snails are certainly interesting, but I think easily confused with MTS if you don't see the two together and see how much spikier the shells are and squatter than the MTS.

Couldn't resist putting up a rednose

Actually a group of them decided with a couple of DAS that the end of the log had something especially tasty to munch on

Very nice set-up mate. I hate to be the bearer of bad news but the 'big black' snail is almost certainly the same species as the smaller black snails - Stenomelania denisoniensis. They can reach up to around 5cm in total shell length. I could be wrong if it continues to grow as there is another snail Stenomelania cf. aspirans that gets to 6-10cm long (I have pics of them in some of my threads) but their shells are a bit different from the ones you have.

the spiky shelled snail is almost certainly Plotia scabra. It has a distinctive shell.

 

 

I can email you the paper I use to ID these snails if you PM me your address.

Its never bad news to possibly have the potential name of an other wise unknown snail. The large black ones have quite sharp angles I guess you would call them where the swirls meet, the photos don't quite do the snails justice. But I do like the almost glowing greenie/ yellow spots they show on their bodies. One that I photographed even has like a little yellow moustache which looks comical and cute at the same time.

Its a nice gold/yellow isn't it? Bob and I found some that are alomost completely yellow, however they dont seem to be maintaining their colour in aquaria and are reverting to look more like yours.

Interesting that the snails would be changing body colour in the aquarium from gold to black, you would expect it to go the other way with no threat of predation.

Knowing how many inverts show some amazing natural glowing capabilities and even display eerie glows under certain light I think these huge black snails would be worth investigating with a good black fluro/ UV light. Especially since they seem to be nocturnal willingly coming out at night but during the day burrowing away under the substrate or hide in the log.

I haven't tried looking at them under a black light. Will have to try it. 

I think the loss of colour must be something to do with diet, something mossing in our tanks that is found in the wild.

      Hey all! I’ve been super busy so I haven’t been active on the forum, just lurking for a while, but I’ve got the time (and a great reason) for a post now.
      Against all odds, I’ve managed to snag myself a group of 4 captive bred honey blue eyes (pseudomugil mellis), an endangered and very rare blue eye endemic to Australia (for those unaware). I’m picking them up locally once I get back from an overseas trip, so I’ll have another post once that’s all done, but I thought I’d set up this thread so I can ask questions, share findings (particularly for other breeders and aspiring breeders) and simply document my experiences with this fish. 
      The group is 2m2f so I’ll start them off in a cycled 5 gallon, which at the moment is just scaped with sand and some inert natural rocks collected from a river bed, so I’ll be chucking in a bunch of plants and maybe an Indian almond leaf or two in order to give them a cosy little breeding environment. In terms of the actual breeding, I think I’ll be using a couple small mops on one side of the tank (one floating, one sitting), and pulling daily for a week or so, perhaps even just a few days the first time so I can work with a smaller group. I’ll be getting some brine shrimp eggs (what are your recommendations for cheapish eggs that are good quality and have a good hatching rate?) for both the parents and the fry, once the fry are large enough. What are your recommendations for a first food for the fry? So far I’ve still not succeeded once with an infusoria culture, despite following a variety of different methods. 
      Obviously, I’ve been wondering about shrimp as well. Would they eat the eggs? If not, which species would be found in a similar region and would be compatible? It’d be fun to have a little bit of a biotype for these little fellas. If I get shrimp perhaps I could order from Dave at aquagreen and get some cool native plants while I’m at it.
      The main thing I’m debating is whether to breed them in a tank or give them a go outdoors. Outdoors seems riskier but potentially more fruitful and a tad easier (because it’s natural), whereas the tank seems much much safer but I’m just not sure how easy it’ll be to get them breeding. Anyways, I’ll see how they go in the tank and reassess later on. I’ll be asking plenty of questions when I pick them up as well, so I think it’ll all work out. I’m very excited to be joining the captive breeding conservation effort for this beautiful fish, it’s honestly been a bit of a dream of mine ever since I heard of the species, and I’ll be pulling out all the stops to make sure this opportunity doesn’t go to waste. I look forward to sharing many exciting posts with these cute little honeys. 
      Cheers, Crabs.

      Hey everyone,
      I was recently (meaning today) given the opportunity to set up a breeding tank for some native inverts (or some harder to breed fish I guess, but I want to go for shrimp) in a fishroom I help out in. I've been trying to decide what native shrimp I want to try breeding, but then I remembered that it's not as simple as exotics. Can I get some input from the 'experts' (@Grubs, @NoGi, @Baccus, @fishmosy, @jayc of course, I know most of you aren't very active anymore, but I would appreciate your help if you see this message) on what native invert you guys think is easiest to breed (for a semi-noob who hasn't kept natives before). I can set it up as brackish I think, we have an archer fish tank there and are setting up a saltwater as well so should have access to those tools and materials.  
      Cheers!

      Hey guys, just found an add for this website showcasing a cool-lookin native algae eating shrimp.
      https://algaeeatingshrimp.com.au/products/australian-algae-eating-shrimp
      Anyone heard of these before or own any? My interest was peaked by the claim that they eat hair-type algae, as I have some on my crypts and lace fern that I cannot remove. And for a price of $4 ea, and super easy parameters, they sound pretty doable! 
      Tell me more oh great SKFians! ?
      (or feel free to point me towards an already existing page)
      post-note: have you/do you keep these grubs? Seems like your sort of thing.

      Fully Aquatic Freshwater Crabs Amarinus Laevis.   Difficulty: Intermediate   Max growth size: 2.5cm across carapace (shell width)   Temperament: Peaceful. Safe with other animals that wouldn't attack the crabs (not suitable with large Cichlids or other large aggressive fish). If underfed. Might take advantage of already weak or injured nano fish or shrimp. Only heard of this happen very few times.  They are great for eating snails. Don't eat plants, only decaying plant matter.    Preferred water parameters; Temperature: 10-28*c can handle colder. Increase air supply in warmer waters. Great for unheated indoor tanks.    General harness: medium to moderate. Just like with snails. Soft water isn't healthy for their shells. Harder, calcium rich water is preferred for healthy moults. Crushed coral, shell grit, crushing some cuttlefish bone and/or feeding them snails is recommended.    Tank size and notes: If keeping only females. A group of 3 is a minimum. Otherwise they'll be less outgoing. The more in the group the more comfortable and outgoing they are.   They have a small bioprint. While we do feed them. They also scavenge and break down food and detritus into easier to be filtered forms. Aiding in a healthy balanced ecosystem.   3-6 female crabs can be kept in a nano tank of 5 gallons (19 litres) given the tank has a filter. A standard 2ft tank (approx 14 gallons or 50 litres) can support up to 20 female crabs. I frequently keep more in less water but only when it's just crabs (plus some shrimp and snails).   If you have a male. A larger tank is needed as males can be aggressive. Preferably doubling the above recommendations. For breeding tank details. See breeding guide write up.   Planted tanks are preferred. Aiding in filtration, providing climbing areas for the crabs and decaying plant matter is bonus crab food.    Reproduction: Difficult. Requires around a dozen adult females, a non aggressive male (rare) and an aged tank. They have a free floating baby stage similar to glass shrimp. The vast majority of this species are female. Males are quiet rare and violent to other males. Often with a harem of numerous dozens of females each.    Feeding: Scavengers that love sifting through mulm and poop. Feed sinking omnivores pellets, sometimes algae wafers. Will eat all sorts of foods. Supplementing with live snails is fantastic. Smaller wafers and pellets (I use 1mm sinking pellets) are better than larger ones to reduce the chance of fighting over food. Pellets with added calcium are a bonus to shell health and moulting.    Additional comments: A truely unique, uncommon species in the aquarium hobby. Lifespan about 2-3 years.  They can survive in low end brackish water. 1.010 SG or less. Making a unique snail eating native that thrives in both fresh and low end brackish.  Plant, shrimp and fish safe in general. Doesn't need or use above water area. Recommend using an air stone if not using air powered sponge filtration, to ensure enough dissolved oxygen in the water column for them. Especially in warmer, tropical tanks.          Breeding Tank setup information:   I have had much success with many types of Substrates and setups. As the crabs are very hardy. My preference due to being cheap and effective is as follows. Breeding these crabs I consider advanced. There are a few important, easy parts to the process that if skipped can lead to failure.    Substrate: Back or side 2/3rds of the base plain River rock gravel (any natural gravel you have laying around is fine). Front or other side 1/3rd sand (play sand from bunnings is cheap and effective. Sprinkle of crushed coral over the substrate.   Decor: Driftwood. Piles of larger lava rock pieces (Washed. Bunnings or landscape supply store real cheap). Dead coral rock if you have any is beautiful to use. (skip adding crushed coral if using this).  Plants are highly recommended. The crabs don't eat plants unless it's decaying matter. Plants help with water quality but also add environmental enrichment for the crabs that love to climb on them and micro-organisms for them to feed off.   I now add a tiny bit of marine salt to their breeding tanks as it slightly increases zoae survival rate. The added nutrients and minerals seems beneficial (however not required) for the free floating zoae.    Filtration: Sponge filtration is best. It provides oxygenation for the crabs and can't suck up the free floating first form zoas the eggs hatch into.  If using other filtration, a cheap sponge covering the inlet is required otherwise all new babies that float in the water column will simply get filtered out. Also if not sponge filtration. Adding an air stone is recommended. Since the crabs are true aquatic. They don't go above water to subliment oxygen if ever there's less than desired in the water.   Equipment: A light on a timer is a good idea especially with plants. The algae build up is a food source. The best food source for the young is green water. Which takes some trial and error to get dialed in.  A heater is not required. I've had them breed in an outdoor carport over Victorian winters. 5°c nights and under aren't rare.   Size: For a breeding pack (1 male and harem of  females) a 2ft tank is a minimum. However 3ft is recommended and definitely will be better suited for survivability. A 4ft would be fantastic, in which the male could have a breeding harem of numerous dozens of females.    Life cycle: a single male will mate with his harem of females they'll form around 200 eggs when berried. After weeks of fanning and cleaning the eggs. The female will release them into a light water flow as the zoae hatch. These free floating first form young drift about just like glass shrimp zoae. Consuming nutrients, green water and dissolved calcium in the water column until they go through a moult into a fully form micro crab. About 1mm in size.   These live amongst the pourus lava rock and in the mulm that should be allowed to build up. Going through numerous moults as they grow in size. Some won't survive moults, some will be eaten by adults (sufficient mulm and suplimentary feeding minimises this). Of one females 100-200ish eggs. Those that survive to adulthood are in the many dozens, not hundreds. The young are a common food source in the wild for micropredators. Of those few that make adulthood. Only 1-3 will be males from my experience. Many of the other males potentially eaten or fought each other at younger ages.   When crabs reach about 6-10mm across carapace is when I remove them into grow out tanks. New young males of this size need to be removed to seperate tanks with a dozen same size females, as they will likely fight other males to the death for the right of ownership of a harem.  There are rare instances where the lionesses will kill their alpha lion if he isn't sufficient or doesn't continue to prove himself worthy. Similar can rarely happen with the crabs. So having same sized male/females is important. Especially at a younger age when the males are still learning how to be alpha. On the other hand. A large aggressive male with a harem of young females can all of a sudden go crazy and kill them all. A balance between the sexes is important. In the wild. The insufficient male or the weak/young females would simply be kicked off the rock and have to search for another group. To replicate this we would need very large tanks or ponds to avoid constant civil war.      I am eager to assist any willing to try and breed these. I would love for them to be far more readily available to the hobby. Demant far outweighs what one can breed themself.
      1st pic is a male standing on a ball of females. When moving large groups into grow out tanks, the crabs will form a ball made up of dozens. 

      2nd pic shows a appropriate mix of Substrates and tank setup. Has all the right components. Illustrating that breeding tanks don't have to be dull and unsightly. 

      3rd pic. A stunning male. Showing their magnificent claws. Note the messy wood. Mulm is your friend when breeding these. The adults sift through for food, the young live amongst mulm, eating it and biofilm. Breeding glass shrimp of other zoae stage shrimp in the same tank is a perfect match. 

      4th pic. A close up of the tank in the 2nd pic. Showing a male and some of his harem of females at feeding time. The male eats first and keeps the females in line and waiting for their turn to eat the pellets that fall near him. Waving his claws around at them as they approach. The crabs like to congregate on a single large rock. Especially on the underside of it out of the light when they're not scavenging for food. Porous rock is better so they can grip and for the young crabs to hide in from the adults that might eat them if hungry enough.

      Hello. I've written the following based on my own time scouring the internet and then personal experiences with my mud crab Gaston.      Mud crab aquarium care.    Tank setup: Minumim 4ft aquarium. A 4x2 ft much better.  Like with turtles, larger footprint is important. Not so much how tall the tank is. Seriously big crabs. Be open to having a 6ft aquarium if you plan on risking tank mates (other than glass shrimp, snails and tiny fish). Unless your in Western Australia, you'll get Scylla serrata aka Green mud crab (not named green for being green. Can be brown and blue also). They can grow up to 30cms and 2.5kgs with 20cm claws.   Have a cycled aquarium with brackish water about 1.006-1.010 SG. Heated 19-25°c. PH around 7 or higher. Harder water is important. Crushed coral can help balance out soft tap water and the use of driftwood. Breaking up some cuttlefish bone in the water column is important. Calcium for shell development. They are from estuaries. So have a great tolerance for temperature and salinity fluctuations.   Decent filtration is a must as they are exceptionally messy eaters. I recommend a sump. The crabs are very strong and can snap heaters, damage power cables and move tubing. So a sump for the hygrometer and heater helps, with the benefit of the overflows and returns being secure. Also clamps to hold parts in place. Pvc tubing can be used to protect power cables and keep equipment protected.   The lid needs to be very secure. With only small gaps and also weighted down. The crabs are strong and can easily lift glass. Some additional glass pieces on the lid to keep it down is recommended.     The crabs will want to get their mouths above the water line periodically. So don't fully fill the aquarium. About 20cm deep. Deeper depending on if you have driftwood or rock climbing areas so it can still reach above water line. Note: ensure all rocks and driftwood are very securely and purposefully positioned. Remember they are very strong and can move unsecured rocks and driftwood. Poorly placed rocks could be moved and break the tank. Using larger rocks and wood is safer than easier to move small pieces.   Sand as a substrate is best. 6cm or so deep. Mixed with some crushed coral and aesthetic gravel. They sift through sand for scraps plus it will help fill cracks between rocks n such to secure them even more.   They will eat plants. So not a great aesthetic addition.     Don't put strong lighting on the tank. The crabs like to hide. Plus they'll grow algae over their carapace under too strong and or long exposure. Glass shrimp will help keep this down.    Aquiring:  Can be bought from a fish market. Sold as live food. About $50 per kilo. A standard mud crab will be about 0.8-1.4kgs. Google how to pic a healthy mudcrab. You want to select the healthiest male you can get (not the biggest). Note. They'll all be male.  Transport in Styrofoam box or esky with a little ice. They'll wrap it in newspaper.   When home. Unpack it (keep the claw string on) then move it into a large container or tank with no water for about an hour as they 'defrost'. Remove the claw holding string as you move into their aquarium. Have a friend around to help with lid for safety reasons.    Feeding:  They are scavengers and eat a wide variety of foods. They will make a big mess when they do, so some glass shrimp, Malaysian trumpet snails and a few tiny fish are beneficial for cleaning up the shower of food particles.   My favourite foods to feed are small whole cooked tiger prawns and marinara mix from the deli. Some white fish cut into pieces then frozen. Repashy with added calcium (powdered egg shells or cuttlefish bones). Make big skeets in flat zip lock bags and freeze. Snap off a piece for feeding.     Can also feed worms, clams, scollops, crab pieces, garden snails, plant matter (like excess Elodea from another tank).  A varied diet is important. But most of all is getting plenty of calcium in their diet. The repashy +calcium or a similar diy mix with agar agar, calcium, seafood and added vegetables is gold.     It might not take to eating well initially. I recommend using long planting tweezers. Carefully. Don't want them to grab the tweezers.   You can train them onto eating by attaching a piece of meat or prawn to some cotton string. Jerk it around infront of him until he goes for it. Might take a few tries. Don't leave large pieces of uneaten food in the tank to spoil. Be very careful putting hands into the tank. They can go from slow to very fast moving in an instant.  Here's my Gaston.

      My parents have an aquarium, so I don't know if this will help, but still want to leave a suggestion. They also liked the idea of installing a light strip in it, so they started looking on amazon. I don't know what went wrong, but it broke on the fifth day of use. I think it was a cheap Chinese thing (although the website told me it was waterproof and durable). They asked me for help finding a better option, and I advised them of the smart LED multi-color light strips I used in my car. Being pretty skeptical, my dad still decided to try them. They have been working fine for a month now and don't even flicker. Mom says the fish are happy, lol. I hope my comment was helpful

      It's not looking good. Quarantine any shrimp showing Necrosis, as it can be infectious. Tell us what your water parameters are, and do a heavy water change after that. Increase surface agitation to get more oxygen into the water. A bit of H2O2 (hydrogen peroxide) into the water to increase oxygen might also help the shrimps that have not yet contracted this.

      Sorry to see you have a problem. Try reading the section on 'muscular necrosis' in the below section. You will need to scroll down through it until you see the bold red heading of that description (it is quite a large article covering many problems etc, it is about the 5th item on the first page);   I don't have any personal experience of this but do ask any questions as someone may be able to help. A bit more general info may also  help, your setup, number of shrimps, how long you have had the shrimps, any water parameters you may have etc?

      Hello, I was wondering if anyone here had any first-hand information on these particular pictures. It describes exactly what a few of my shrimp have. The second picture is spot on and most accurate. Thanks
    • Crabby
      #4 looks almost like a juvenile female to me, just looking at the abdomen in the top left image, but definitely looks more male in the other two images. The colour suggests it is an adult though, and it’s lacking a clear  so Simon is probably right in thinking it is male, that top left image is just confusing me a bit. If you’re going to get a female, to be sure, make sure it’s got an obvious yellow saddle. That’ll help you know it’s mature as well.
