I did research I always do and my research is conflicting with this thread and what the store told me. but I trust this forum more. current tank size is a 75 growout. as all the fish are around 6inches. it has 2 aquaclear 110's for filtration.
those tanks are too small for the lung and maybe the clarias, and store isn't research. u should do better research, African lung aggression is one of the first basics.
pole. Ive done my research on this forum. and others. I have a 300gallon Rubbermaid and a 180gallon and friends with 500 gallon plus tanks. the fish are guaranteed a long happy life. I just thougth since the store told me I can keep the lung with other fish and it was in with other fish that I was okay to mix him in a tank. i guess I was wrong I am selling the knife fish. and putting the clarius in my 90 gallon until his big enough for my 180
