Last weekend I bought an Amano shrimp and the next day I found that he had been sucked up into the AquaClear filter. He was still alive, but a few of his legs were ripped off from the impeller. It is now a week later and the shrimp has been doing fine. I have since covered the filter intake with a filter media bag, so this shouldn't happen again. Does anyone know if his legs will regrow over time?
