Blue Velvet Shrimp

Recommended Posts

So I lost 3 shrimp today - two out of my 8 Blue Velvet Shrimp and my one Blue Dream. I don't know why or what the cause was although my guesses involve either overfeeding or possibly water shock from a small water change. 

My parameters are as follows: 

GH: 5-6

KH: 5

PH: 7.6

Nitrite: 0 ppm

Nitrate: 0.25 ppm 

Water temp: 68-78 degrees F 

My water is tinged green and I have 4 live plants (including a Java fern), a moss ball, an Indian Almond Leaf, and a Rock in the tank itself as well as one small snail. I got  a siphon pump today to be able to do easier water changes. How would one go about water changes in an area that is a bit colder than many other places? I started using cold water after making a mistake on using hot water which could have been a problem... but now that things are a bit more in place I want to try and get stuff settled. 

If I got more shrimp: how long should I drip acclimate? 

What would be the best way to use tap water for water changes when I only have one heater? Or would I want to use distilled water? 

How often should I feed the shrimp? I keep reading all sorts of different tips and views. 

Is it okay and normal for shrimp to hide under the rock? I have some (4) pretty small and pretty transparent shrimp that I haven't seen since I introduced them into my tank. I don't want to move my rock and find dead shrimp underneath...Maybe I should just give up? I don't want to but maybe I should figure out what is up with my tank first. Because I have no clue why this is happening. Is it my Nitrate and Nitrite levels?

For as long as you need. To get the same water parameters as your tank.

This is where a TDS meter comes in handy.

Drip the water into the main tank slowly. Assuming you have matched the water parameters of the new water, than dripping it into the tank slowly will not alter the temps of the new tank.

Not sure how distilled water fits into the previous question of heating water changes.

You'd want to use RO, distilled or rainwater to gain greater control over what goes into your tank, so that you can set the ideal parameters yourself. Tap water has all sorts of chemicals that impact water parameters, and not all of these chemicals are useful to shrimp or fish. So RO, Distilled and rain water takes out all those chemicals, so you can put back in just the right amount and only the essential minerals to sustain life.

How often should I feed the shrimp?

Once every 2 days. 

But if they don't finish all the food, I usually leave it in. But I wont feed for another 3-4 days depending on how long the food lasted in the tank.

If there are no predators around, than it is not normal.

This could be a general indication of sub optimal water parameters. Something is wrong if they are hiding too much.

What is the Ammonia levels in your tank? That is the crucial parameter. Crucial in the sense that this parameter will kill. Ammonia needs to be zero. Where as Nitrate is a long term issue. It doesn't kill as quickly as ammonia.

Thank you! I am trying to make sure everything is good to go - and I want to take good care of my shrimp for sure. I just ordered an ammonia API test kit (I believe chemical tests provide more accurate results compared to the strip tests) and a TDS pen on amazon so I should get those Wednesday. I will try not to mess with my water too much until I get the necessary things I need. I am glad things seem to be so-so for now. I drip acclimated for 1-2 hours when I got my blue velvets with the current water in a specimen container and dripping tank water into the container itself.

Maybe I'm nitpicking, but 68-78 F? That's a pretty wide range. How have you been doing your water changes? Dripping the water slowly or just putting it in? That can temperature shock the shrimp. Cold water is better than hot (funky pipes and all) but if you're giving the shrimp a temperature shock in doing so, it could be just as harmful.

Rather than using "time" as a guide we should use the water parameters as the reference of when the shrimp/fish has had enough acclimation. 

Now that you have (or will have) a TDS pen, you just need to measure the TDS of your tank and the water the shrimp came in.

Lets say your tank TDS = 150. And the water the shrimp came in = 200.

So you start dripping water into the bag the shrimp came in. You keep dripping until TDS is close to 150 (TDS of your tank water). Say 155 TDS should be ok. This take as long as it needs to reach close to 150TDS. It could be 1 hour. It could take 12 hours. This is why I will hesitate telling someone that 1-2 hour drip acclimation is enough. It all depends on the start water parameters and how fast the drip is going.

Anyway, good luck, and I hope you sort the issue out without too many more deaths.

Sorry to hear you lost some shrimps!

How big is your tank and how long has it been running? Did you do the 'cycle'?

When doing a water change you should drip the new water into the tank. That will illiminate the temperature difference problem and any difference in parameters between the two waters.

When acclimating new shrimps you should drip acclimate them as long as you can, the longer you do that the better chance they have of survival. You will need to match the water temperature to that of the tank by floating the container with the shrimp in the tank once you have stopped dripping, before adding the shrimp to the tank!

The parameters you have I would think are acceptable so I would stick with tap water if that is what you are using, for now. RO water is ideal but you will then need to buy GH/KH+ to add the minerals. As I say, I would hold off using RO/distilled water for now until we can pin point the problem.

If your water has a green tint to it that may be an algae bloom? A white tint is usually a bacteria bloom and I have only seen that whilst a tank is 'cycling'. I think an algae bloom will mean there is less oxygen in the water as the algae absorbs it??????

Overfeedinng is very common. It will depend upon the size of the tank and how long it has been running etc. With only a few shrimp there may actually be no need to feed additional to the natural biofilm of the tank. As shrimps are feeding all day on biofilm it is usually better to see additional food as just a treat and feed very sparingly. Overfeeding with shrimps doesn't usually mean that the shrimps over eat, it usually means  too much uneaten food polutes the water and if you have green tinted water, algae bloom, that may be why? There usually comes a time, if you are lucky, that there are too many shrimps in the tank for the biofilm to sustain on its own, so as the population grows feeding may become more necessary.

Shrimp don't usually hide unless they are new to the tank or there are fish etc (even then they will usually adapt to them) or as JayC says, their is something wrong with the water quality?

I haven't been able to find an ammonia test kit so maybe that was my problem but I woke up to no dead shrimp. Before I do a water change I want to make sure my water I have is correct with water parameters and GH and KH  especially. I did cycle my tank and it should be fully cycled by now. 

 

Thank you all!

      The in depth guide to keeping as well as breeding Amarinus lacustris by Hervey Doerr-Rolley
       
      Overview
      The aim of this article is to educate and warn people of the mistakes I made and how I was successful with breeding and keeping this species. I published an article about this species several years ago so thought it was time for an updated guide for anyone wanting to keep and breed this species. All my knowledge about this species has been developed over the 4 years I've kept this species as well as the many scientific articles I've studied, I first kept this species when I was 15 and now 19, my colony is still going strongly. Currently studying a bachelor of Marine science. Firstly I'd like to point out this species does not have a larval cycle, it is a far too common misconception people have. I believe this thought is derived from their much larger cousin the Amarinus laevis and the Thai micro crab, Limnopilos naiyanetri. Amarinus lacustris have fully formed offspring, meaning their offspring are essentially miniature adults once hatched from their egg. Some points of interest about this species, there are 8 instars before their pubertal moult. Females up to two moults before their pubertal moult can copulate and store spermatozoon, once she reaches the pubertal moult she can then impregnate herself without the need of copulation. The stored spermatozoon can then be used up to 15 separate brood cycles (15 clutches of eggs). Adult females can carry up to *35 eggs (anecdotal) and take around 25-30 days at 15 degrees Celsius to hatch as fully formed offspring. 
       
      Water chemistry
      A. lacustris have a strong preference for hard water, I keep and breed mine in;
      pH: 8-8.2
      Ammonia:0ppm
      Nitrate:0ppm
      Nitrite:0ppm
      KH:125ppm 
      *25% water changes are done weekly*
       
      Breeding and Husbandry 
      Key points for their care;
      Gravel substrate - fine pea gravel is best.
      Air pump sponge filters are essential as this provides cleaner water as well as a feeding ground for the offspring as well as adults.
      Mulm and moss are essential.
      A good rule of thumb from my experience is 500ml of aquarium space per baby-sub adult, and then 1L per adult crab, this allows for less aggression from male to male behavior. It is up to you but the less stocking density the better due to the aggression of breeding from males, keep in mind this aggression is only towards other males however females that are being copulated with may sustain serious injuries if too many males are kept together. The best ratios are two males to 8 females. When a female sheds she releases hormones into the water column just like shrimp, if any of you are familiar with breeding shrimp you can note this by the erratic and fast speeds the males zoom around the aquarium searching for the female, this is the same case with A. lacustris except the swimming, rather they crawl quickly around the aquarium in search for the female to copulate with. Once the male finds the female he will grasp the female tightly underside to underside in a 'hug' embrace, he will then fertilize the female. This embrace can last minutes or hours depending on the male. Eggs will soon become visible and as described above hatch within 25-30 days*. This species is a cold water crustacean so you must remember that, breeding will cease if the temperature goes above 22 Celsius. Keep them in a mature mulm filled aquarium with leaf litter (I use oak leaves) with plenty of hiding spots and moss, a 8pH and 15 Celsius and before you know it you will have berried females.
       
      Feeding
       
      Surprisingly my A. lacustris do not eat commercial foods, I feed mine cultured white worms which are perfect as they grow to a max size of 3cm and survive underwater for several days. I also add snails to my aquarium as the crabs feed on their feces. Funnily enough baby crabs will eat the white worms too once they are 2 instars old, so it is not uncommon to see a 2mm baby crab hanging on to a 2cm long white worm! I feed my crabs every 3 days and small amounts of the worms to reduce water quality issues.
       
      Common questions I am asked 
       
      As I was the first person in Australia and the world to raise fully tank raised F2 offspring i have come across many commonly asked questions. "can I get these crabs in country x?" so far you can legally only get these crabs in their native geographical regions, however once these crabs are even more commonly bred their popularity over the Thai micro crab will be clearly abundant simply due to their ease of breeding which you know, therefore I wouldn't be surprised if these hit the international market once they're being large scale bred. "Do you have any for sale?" when I have crabs for sale I have a waiting list, If you want to ask questions or be on the waiting list email me: [email protected] "can these go with fish x?" if the fish is 4cm or less they are fine generally, my opinion is keep the species only or with shrimp which leads to the next question "are the shrimp safe" and yes they are, however they are naturally scavengers so if you have dead or sick shrimp they will eat them, if your shrimp are healthy they will not predate on them. "how long do they live for?" they live for around 2-3 years+. "why are all my crabs dying" this question is addressed below; 
       
      Major issue that needs to be addressed 
       
      Since my first sales of A. lacustris I suddenly saw a spike of ads for them in Australia, unfortunately I could tell the individuals for sale were all wild caught and at best had only lived in an aquarium for a couple weeks of their life. This then would result in people encouraging the decimation and local extinction of the species in our waterways due to peoples greed of wanting to make a quick buck off this amazing native species. The crabs that I breed and sell are all aquarium raised individuals ONLY, I have put time, money and effort into the crabs I breed to ensure I do not impact the wild populations and offer aquarium suited specimens for people wanting to keep them. I have had a plethora of emails from people asking me why crabs they had sourced outside of my individuals had suddenly died off, this is simply due to the fact these crabs have not been aquarium raised and selectively bred for years like mine have. I find it horrendous that people think it is okay to collect many wild individuals to then sell knowing full well they will die within around a 3 month period just for their sake to make some 'fast' money. So please before you buy from a seller of these crabs ask as many questions as you can to find out how many generations old your crabs are and how long they've been bred for etc. If they cannot supply a high amount of detail or simply quote my articles about them do not buy from that seller. Do not support poachers for your aquarium! This applies with all species, worldwide.
       
      Thank you for reading my article,
      again if you have any questions feel free to email me as I'm always happy to help out ethical keepers and potential breeders of this species.

      I am doing an experiment with my cherry shrimp on temperature dependant sex determination and I need a divided tank
      obviously the tank won’t need to be too big as I am just housing 1 male and 1 female in each section.
      ideally, I am looking for a rectangular tank divided into 3 sections so that I can breed 3 pairs at once. The sections will need to share water as I only want to use 1 set of equipment. But if they’re sharing water, I am concerned that after breeding, shrimplets will be able to move into each section through the holes which would ruin my experiment.
       Does anybody know where I can get a divided tank suitable for my experiment that isn’t too costly or anything I could use as an alternative? Thanks

      Hi team,
      So I am really excited by the unreal shallow aquscaped tanks that I see online and I love the idea of keeping shrimp.  I have some native red nosed shrimp breeding in a pond outside but really want to put some red or blue cherry shrimp in an aquascape where I can see them do their thing.  

      ada 60 F  60x30x18 is the right price and I see beautiful examples online but I feel 30 litres is not enough, especially considering hardscape and soil going in. (what do you think?)
      ada 90 F 90x30x20 would be my ideal choice but its sooo expensive. $600+ and then freight to Bundaberg! (Wife says no)
      Mr aqua Komoda 3ft 90x30x30. - great tank low iron glass but the dimensions are losing the shallow look
      Mr Aqua Komoda 4tf 120x30x30 - great tank, low iron glass - lots of room for shrimp and a school of celestial danios or chilli rasboras - dimensions might work for shallow look, but lights, plants and filtration getting expensive at this point (plus freight!)
      lastly and temptingly Mr Aqua 12 gallon bookshelf - 91x21x24. But I cant seem to find low iron glass version in Australian shops?  (or are they low iron?). This tank would be perfect but I am worried if I get this tank(one shot at getting it right) I might be unhappy in the long run?
      Do you guys have any preference here? ( which one and why?)
       
      Am I missing any ultra clear shallow tank alternatives?  I have seen some mention of FireAqua bookshelf tank online but I cant find a retailer.. and I see you guys talking about aquamaxx tanks but where do I get one of them?
      Thanks so much for your time and efforts- if you have a tank pref can you suggest the light you would pair it with?   It will be a low tech planted tank (wife says no CO2). 
      Budget around $800 for setup of tank lights and filter maybe ( obviously less means plants and shrimp can be added sooner!)
      any advice welcome.. 
      cheers sub

      Hi I'm an animal enthusiast with many frogs snakes and arachnids but it's my first attempt at caring for cherry shrimp..i researched with my girlfriend quite a bit and already set up a planted tank in a nano 2.6gallon aquarium. It will be cycling and until then I just wanted some feedback on how it looks and what y'all think about it? Thankyou ~

      About 3-4 weeks. It depends on your quality of water and the iodine of activated carbon.    
    • jayc
      Keep doing this, and feeding it the medicated food. If the shrimp doesn't eat the food within a day, remove it and feed new medicated food again the next day.   You sir, are a good candidate for an RO filter. Your shrimp are not going to like the hard water in the long term.
    • alkemist
      The shrimp is in a separate container, but it's been in there for a week or so now. I see it picking off the air stone and the sides of the tub. There is shrimp poop in the container, so it is eating, just not the food I give it. I suck out the detritus and excess food every couple of days and do small water change daily. At first I used tank water, since I don't run R/O. I use a combination of hard tap water with a little water ran through my water softener (I know it's a bit taboo to do). I don't know an exactly how to re-mineralize it to keep the shrimp from going into shock if I used straight clean tap water. I am starting to slowly remove the water from the tub and mixing it with direct tap water with the water softener on by-pass, so hopefully it can acclimate to full clean tap water. With the shrimp feeding, should I try to remove all visible signs of food and fast it for a couple days and then try again?
    • jayc
      Is the shrimp still in the main tank? Or have you moved it into a separate container? There should be no biofilm in a new container, and it should be hungry to want to eat the medicated algae wafer. It won't go away without treatment. The bacteria is not just on the shell (carapace), so moulting won't get rid of the bacteria.
    • alkemist
      I've tried to feed the shrimp food soaked in the oregano oil mixture (1 drop of oregano and 5 ml of water since it's 86% carvacrol). The shrimp seems to hate the taste of any food I put in there with the mixture. It goes off and tries to feed on anything but the medicated food. I don't have any other food in the tub and took all the floaters out but seems to be feeding on naturally growing biofilm now.. I'm not sure if I am seeing any results. Should the reddish brown spots go away on it's own or does the shrimp have to molt it off? I've noticed it's been scratching itself a lot.
