Reply With Quotedid you cycle your tank properly before adding the crs in?
and did you introduce the crs to the tank via proper acclimatization?
imo your tank is kinda small even for that numbers of crs to be kept
so this is another thing you may want to look into
Hi all,
I have a nano tank which i have about 13 CRS (B and C grades) inside and until now left about 7 of them. One casualty per night which is very costly for me. sob sob.....i have no idea why the CRS are dying slowly one by one. My tank is those very small type...12cm by length. Have a stone tied with moss inside the tank. PL light on from 3pm to 10pm at night. I am using those black quartz gravel in the tank also. Did not check the pH though as i do not have a test kit. Any advices? Thanks
regards,
Alan

Since you mention your light on from 3-10pm,what is your tank temp ?
Tank temperature is about 28. Is my tank overpopulated?
First question... Did you cycle your tank? You need to run your tank for around 4-6 weeks for your tank to be fully cycled...Originally Posted by alantan9
2nd question... Since you mentioned that you do not have any test kits I assume you did not test the water parameter before you released your CRS in your tank... If you do a search you will know that you need to have a certain parameter for your CRS to survive...
3rd... CRS prefer a lower PH environment in the range of 6.5 so this could be cause as well...
4th The black quartz could also be a reason why your CRS are dying... I've read that certain quartz release toxins in the water... A ideal subrate would like ADA, GEX, Magic Soil, etc. These soils lower the PH in your tank...
CRS can survive at that temp & in this case I do not think it is the reason for the cause of death...Tank temperature is about 28. Is my tank overpopulated?
Never create what you can't control
Even if the tank is cycled, I have doubts that the biological filtration (if there is one because it is not mentioned) would be able to support the bioload as the tank is really small (12cm).
I would suggest no more than 4 CRS for the tank, unless you don't mind doing water changes every few days to neutralise the waste. I would also think that it is really difficult to control the parameters of such a small tank, any small fluctuation is actually a really big change to the occupants of your tank. Do consider upgrading a larger tank (30cm), the parameters are much more stable to ensure easier management and better success.
I agree with Quixotic a small tank is difficult to maintain the water parameters... I'm using a 3 footer with about 200 litres of water as it is easier to control the water parameters...

I believe the bro there already given you some ideal how to keep CRS or maybe you should do some research and reading before you start introduce more CRS to next world... and for the temper. 28C is a bit too high for CRS maybe you can put one cooler fan to lower your tank water temper.
Hope you can success
You need to setup the tank properly. Not recommended to use smaller tank, as it is very hard to control. Read my blog on setting up a CRS tank. It's not rocket science, but you need to understand why cycling of tank is important. On top of that, you need to get all the water parameters right before you introduce the shrimps into the tank. Regardless of what shrimps you are keeping. Especially CRS requires extra care, compare to other shrimps.
