Last week i came home to find my 7 inch. polypterus' tail hanging out of the mouth of my 9 inch wolf fish. I couldn't believe my wolf fish could have swallowed him. In the tank i also have two 12 inch Red Bellied Pacu, one 12 inch clown knife and a 6 inch peacock bass. I think that the wolf fish ate the polypterus because i fed them feeders the week before, and he was hungry again. I don't want the wolf to eat my peacock bass too. Is there anyway i could avoid this from re occuring
