My green wolf eel has gone mad, he tore my spider crab into like 10 different pieces. He also will not eat any feeder fish I place in the tank. The only thing he does is gets my snails and throws them around the tank. I do know what to do. The only guess is that it may be matting season for eels, because Awana Pets green wolf just laid eggs? Also how do eel eggs become fertile?
