75 Gallon Fish Tank Stock?!?

Nope first guy is wrong!! If the fish has grew up together they will do just fine! Just make sure you give them hiding places. The Bichir might give you problems, they will eat anything that fits in there mouth. The chinese algae eater will be fine also yes it can get testy at times but if enough hiding places are there they all will do fine! I have been raising and selling fish for 10 years now
