I am looking for some information on the Gold Severum. I have a 56 gallon tank, I know the fish is about 5-7 inches ( I am buying him from a friend) I want to know what kind of tank mates I can put in my new tank with him. He is currently with a ghost knife a group of schooling fish, some plecos and catfish. I really like the blood parrot, convicts, ghost knife,& am also looking for schooling fish, Ruby barb? or tiger barb? I want to know how many and what kind of fish will do best with my new Gold Severum. Please help. I have always had single fish & sort of want a comminuty tank. My last fish was a 8-10 inch Red Devil. Please Help me! Thanks!
