I have a 90 gallon tank with mostly African cichlids such as yellow lab electric blue cichlid red zebra venustus Acei yellowfin borleyi ob cichlid bumble bee and a couple more African cichlid mixed with a green terror jack Dempsey black convict a channel cat fish and a pike fish and one or 2 more South American fish I've had this tank set up for about 4 months and all of the fish get along but they are still on the smaller side the biggest being around 4 inches my question is will they be on as they grow older
