I have a Golden Severum, Convict Cichlid, 2 Blood Parrots, and Jack Dempsey in a 55 gallon currently. In a month, or so they will be moved to a 75 Gallon. Will a Gymnogeophagus fit in as a good tank-mate for my fish?No aggression right now, and My Jack Dempsey is supposedly a female and very laid back and young. I am trying to see if I want this Geophagus now so at least the aggression won't be as bad if it grows up with it's tank-mates now. If I were to get it from my site, it would only be 1'-2' inches btw. I am prepared to upgrade to a 120 if necessary but i don't think so.....
