I have a standard 75 gallon with a 3" green sunfish a 2.5" JD and 2 3" GTs. The GTs aren't going to stay. theyre here to spread out aggression until i figure out my stocking. My green sunfish is boss and likes to remind his tankmates of that quite often especially if he's kept with only one other fish. So before I get rid of the terrors i want to find a distraction or two for him. In a 75 do I have enough room to add a convict, maybe 2(same sex). Also how well have silver dollars worked for people, how many of those would i need to keep and is my tank big enough, also the only question that matters. do your other cichlids actually go after them? Are there any other convict sized cichlilds that would do ok with a couple monsters? I know this is way more than one question. any other ideas on how to keep these two together would be appreciated. Thanks in advanced.
