I'm wondering is there anything a single male convict can coexist with in a 55 gallon? A female convict is out of the question, I do not want all those fry, and selling them/feeding them to another fish/disposing of them isn't in question either lol. I've heard of them being kept with raphael cats, but I've also heard of them plucking out their eyes. I've heard of jack dempseys, green terrors, and firemouths hanging out with them ok sometimes, then there are the stories of them getting their asses whooped. So, have you guys ever had success keeping a single convict in a large tank with at least one other fish? I'd love to hear about it lol. If not, I guess he'll get his own tank.
