I have two Jacks who are about 5 inches and are outgrowing there 55 gallon tank which they share with a mated pair of cons. They get along great but I wanted to move the Jacks out and get a newer bigger tank but I wasn't sure of the size because I wanted to put them with other fish, so i wanted to know what fish peopel have found they get along well with...So If people could tell me what fish they recomend then what tank size they suggest it would help me alot.
