    Mysterious deaths

    Hi! I know this has probably been asked a million times before but my shrimp keep dying and it's truely a mystery and being very new to shrimp keeping I'm hoping someone can help. Sorry this is long, tia! I cycled my 21L tank for 2 months with plants (anubias on driftwood and hair grass with some floating rotala) I use Seachem Prime and Stability. I tested everything and all was fine (we keep fish so I'm not new to water parameters just shrimp) I put in 3 large natives (pictured) and a pack of 10 glass shrimp I ordered from livefish. All of the glass died within the week but the natives (transferred over from my housemates tank) are still thriving and have even shed the other week and grew a little. I feed algae wafers every 3 days and Hikari shrimp cuisine every second. Did a small water change last week (10-15%) and on the weekend put in 2 cherries and 3 glass from an aquarium shop in. One of the cherries is dead and the others except 2 are hiding and I havnt seen them since the first day. I've noticed a few detritus worms on my glass, could it be an oxygen issue? Temp is at 23°c same as housemates tank but the aquarium shop didn't seem to have a heater and livefish sent the glass in bags that arrived cold I floated the bags and let a little of my water in for about 40 mins before setting them free.

    Hello

    Hi all,I'm relatively recent to fish and shrimp keeping. I'm a freshwater ecologist in my day job, but only got around to keeping the fish and shrimp In the last 12 months.And now I've got 4 tanks and I'm wondering if my wife will notice if I add another!I've got a 215L Aquaone 980 heavily planted (DIY CO2) community tank in our living area (pearl gourami, kribensis, ottos, hengeli raspboras, Cardinal tetras and Cory sterbai).I kitted out the walls of our garage a few years back with about 10m of floor to ceiling storage racks to keep things tidy. Only now it's being converted to a fish den. In the garage I've got 2x 2ft tanks and a 40L quarantine tank.One of the 2ft tanks is heavily planted with DIY CO2 and 22W LEDS. It's got RCS in it at the moment and some Neon Tetras. The other 2ft tank is being prepared for CRS.And finally the 40L quarantine tank currently has 5 native long arm shrimp in it (Macrobrachium australiense). But they are absolute assassins (the victims so far include 4 neon tetras, 2 barbs, and one black widow tetra) and are about to be sold off to a good home. CheersPaul
  3. After doing some species counts I was pretty surprised at how many native shrimp I currently have. First is what I am assuming are local grass shrimp, which I easily catch with macrobachium, just the macros I tend to put back in the wild rather than keep. Then there are Riffle shrimp Chameleon shrimp Darwin Red Nose Shrimp Darwin Algae Shrimp Typhus Shrimp And a large macrobachium looking shrimp that I have never formally identified. I did have the other type of Red nose shrimp that doesn't breed in fresh water which I think has now died out in my tanks. I did have Barney Springs shrimp which I think have either since died out or are disguising themselves in with the Blackmores. The zebras I had I know sadly died out. I also have some native snails which I am pretty chuffed with and then some native fish such as Threadfin rainbows, spotted blue eyes, Pacific Blue eyes, locally caught rainbows and Streets Creek rainbows, pygmy rainbows and in the back pond I am pretty sure their are still come purple spot gudgeons. Never did I think I would end up with so many natives and still be on the hunt for some other elusive natives like some local Rhads.

    Red Paratya

    I've been meaning to start this thread for a while and I intend to keep it going for some time. A couple of us down here in Melbourne have known for a quite while about a coloured population of Paratya shrimps. A few had been collected but when the shrimp fever really hit me in 2009 I decided to collect a few and have a decent try with them. My big plans came to nothing, which of course is the same as most other's experience with this genus. Please note, these photos are 5 years old and I need to collect this form again before I can post any more. In the next couple of months that will happen, and my big plans will start over again. Red Paratya with typical specimens: close up crop: more specimens: berried female: In this population there are black shrimp, blue shrimp and red shrimp. Some blacks have a blue base colour and some have red. This is an interesting parallel, I think, with Neocaridina davidii. However, these Paratya change colour radically which is quite different from cherries I've seen at least.
  5. A mate and I just returned from East Gippsland after a couple of days running around hunting various things. As is normal for us we left Melbourne about 10pm thursday and drove until about 4am - that way we maximise our time out there and don't spend a potentially good day sitting in the car. We had a few objectives for the trip and as normal only fulfilled some of those. Our primary goal to check the last possible location in Victoria for a generally NSW Utricularia species (uniflora) had to be aborted for the second time, this time due to track closures and an approaching severe thunderstorm. The site is so remote it's no wonder that nobody gets out there. Next time we'll need a chainsaw in the car to get through. BTW I intend to bore you all with this non-aquarium stuff before moving on. Deal with it! A secondary goal was to photograph an orchid species in the same general area, which we did achieve: Dipodium variegatum, near Mallacoota Another secondary goal was to see a couple of tree frog species in the rainforest pockets out there. Litora citropa (Blue Mountains Tree Frog) is known from Victoria these days but we couldn't find any adult frogs, a shame as neither of us has seen this species in the wild. Litoria nudidigita was the other target and we found them in abundance. I have seen these before when they were still called L. phyllochroa but my mate had never seen them. Hunting frogs around rivers at night is not something I carry my camera for, so fortunately we also found one during the day: Litoria nudidigita, near Cann River We saw some interesting things walking around the rainforests. Unfortunately it was very dark and I discovered the tripod mount had fallen off my camera somewhere (doh), so the shots are all handheld and pretty average. For the flowers below (and frog above) I was standing on tip toes and just couldn't set the focal plane where I wanted. Asclepiad species (something like a Hoya) another nice tiny flower Thurra river tributary - typical sandy bottom and tannic water Forest floor We bumped into a young German bloke traveling alone and for his benefit I grabbed a nice male Water Dragon for him to photograph. That made his day, so a minute later my mate saw a White-lipped snake and I grabbed it too as it raced off the path. As I picked it up I saw the Tiger stripes on it and realised the mistake. We all got an uneasy laugh out of that but I think the young tourist will remember that walk for some time. Sorry but my hands were too full to get photos. Something I've only seen a couple of times before is the larvae of a butterfly - Jalmenus evagoras, the Imperial Blue Hairstreak, with its attendant ants. In the same way that terrestrial orchids fascinate me because of their reliance on a symbiotic relationship with mycorrhizal fungus, the butterfly family Lycaenidae (blues) fascinate me due to their symbiotic relationships with ants. The ants protect the caterpillars and pupae and are rewarded with a sugary secretion from the butterfly larvae. Nature is wonderful. At another site I was able to photograph a pretty amazing dragonfly, despite having the wrong lens on the camera. Eventually he allowed me to sneak close enough to get this heavily cropped pic: I'll wind up "part 1" here because of time constraints and prepare myself for part 2, which will mainly cover mosses, shrimp and their habitats.
  6. While the east coast of Australia is home to Paratya, this complex of species does not occur in the south west of the country. I wondered if they even had "glass shrimp" over there, so before my last trip I started trying to find out. Of course they have glass shrimp - what area with enough water about doesn't? Over in SW WA they have Palaemonetes australis, a lovely shrimp which as it turns out is very widespread and occurred in every likely looking river I sampled. It's a bigger shrimp than most that we keep, probably 5-6cm total length from memory. It's fairly variable but unfortunately has tiny eggs - at least at the locations I checked - so it's difficult to raise the young in aquaria. I would love to give these a more serious try one day, so I wonder are any WA shrimpers keeping these? Or will they after reading this? Palaemonetes australis: I wasn't sure if this should go in "field trips" or here, and decided to make a different post in each section. In the field trip section there will be more shots and some other stuff too. Make sure you have a look!
  7. I was lucky enough to cruise around SW WA a few years ago looking at some of the things that interest me. Of course, aquatic life was one of those things and I got to see some fish that I'd been interested in for ages. The Salamanderfish (Lepidogalaxias salamandroides) was probably the most significant, and one of the dwarf Galaxias (Galaxiella nigrostriata) was another exciting one for me. I do love to find the eastern species of Galaxiella (pusilla) when I'm out and about back home in Victoria. I travelled from roughly Albany across to Dwellingup, not too far from the coast just south of Perth. Along the way I looked in every waterway where it was convenient to stop and found the south-western glass shrimp Palaemonetes australis virtually everywhere. They varied in colour to a certain extent but were always pale speckled and with transverse pale bars. They grow quite large compared to the shrimp we usually keep, about 5-6cm total length, and are really pretty attractive little guys. I heard stories of nice colour forms occurring closer to Perth, and I can only hope some of you Westies get out and collect from a few spots in the hope of finding some. Then you can send some to me too! We headed to Dwellingup for a mates wedding and spent a few days hanging around there, so I was able to check the river there most extensively. The Murray River, as it happens. This river was made up of large open pools interspersed with short rapid sections. We had the canoe in and were able to negotiate upstream through many of these rapids, occasionally having to drag the canoe over rocks to continue. The downstream return trip was invariably much more fun. Murray River at Dwellingup, WA: Palaemonetes australis from Dwellingup: I found some other nice western fish here, including Tandanus bostocki, Bostockia porosa, Edelia vittata and Galaxias occidentalis. Sorry no photos of these fish. For those who don"t know, Tandanus bostocki is a small version of our eastern Tandanus tandanus, and Bostockia porosa (Nightfish) is a dwarf Percichthyid, essentially a mini Murray Cod. The Edelia and Galaxias are the Western species of Pygmy Perch and Galaxias. However back towards Albany at the start of the trip we stayed at a farm Below the Porongorup range. They had a spring fed waterway which had been protected from the usual farm activities and was quite intact. There I found a lovely little Goby, probably Pseudogobius olorum or a related species. Unfortunately my pic of the waterway was too large to load here so perhaps I'll think to resize it later and try again. I do have pics of the origin of the spring water supply and of the Goby. Porongorup Ranges - where the water came from: Pseudogobius olorum? People near Adelaide can also find Pseudogobius olorum (or a similar species) close to home. It's widespread and may have been split up. Obviously, it's time for everyone to get out and about on a field trip to see what's just around the corner from home. We truly do live in the lucky country here in Australia.
