I have a 75 gallon tank with 4 cichlids all under 4 inches. I have a Jack Dempsey, Convict, Salvini and Green Terror. There is also a Royal Pleco of similar size in there with them. All of the fish have established a territory/pecking order. The JD is a little skittish and the Salvini tends to lurk in amongst some drift wood. I would like to try to bring those fish out with some additional fish. I know all of these fish will grow bigger and I plan to move them to another tank when the time is right. For now I would like some extra movement in the tank. What are peoples thoughts or suggestions?
