What to do with this crab
Hi. I have captured a small crab using my own variation on the 'tilted glass' method (so thanks to all those who described that...it was very useful). I'll post a pic later in the Identification section so someone can try to ID it for me. Meanwhile what to do with it? I have it in a large jar of tank water for now. I don't have a sump or refugium. I do have a small tank that I am cultivation rotifers & copepods in. Would it be OK to put it in there or will the crab eat all my rotifers?
Thanks for any advice.
