Ok so im going to be buying my uncles 150 gallon and that will be my main tank eventually. I have a common wolf fish, a loiselli, a jag, and a clown knife fish. I am also growing out a pair of hujeta gars in my fiances tank. What fish should i put in the 150. I thought about the wolf getting his own tank but wanna know about sizes/ I've heard a 50 gallon breeder would be good for an adult and also a 75. Anyone?
