[CICHLID34]

So i too the divider out of my tank to make sure my wolf fish and loiselli would get along befor they went into their bigger tank. Well the loiselli is beating on the wolf a lil bit. I dont want eaither one to kill the other. So if they were yours which would you trade in. There future tankmates are

clown knife
jade goby
red tail barracuda

Life time tank will be 150 gallon as soon as i pick it up at my uncles
