Are there are peacock bass species that will fit in a 90 with CA/SA cichlids? Also, I heard that they stink up the water because their body emits it thorugh their skin, is this true?
Sorry...no can do. You could keep him in there till about a foot long (1 year or so) but then have to either upgrade to a bigger tank or give him away/sell him!
even a 1 foot fish is pushing it in a 90 which is only 18 inches wide. That is why I am planning on upgrading this summer to at least a 24 inch wide tank the height of a 90 doesn't do the fish any good most of the time.
