Rainman may also be able to provide good insight. I think the others are correct especially if you do not have a large biological filter in operation for the grow tank. ""The only symptoms I see from them is lethargy, loss of appetite, and physically their underbellies are sunk inward. I did an autopsy and when I cut into them, a green fluid came out."" These symptoms in crowded conditions sounds like ammonia poisoning. The green fluid is bile fluid from the gall bladder; you cut it during dissection.
