Would a female Bluegill and a senegal bichir be able to co-exist peacefully in a 55 gallon aquarium? It is extremely well filtered, at the moment the sen is aboit 4" and the female bluegill is closer to 8", I'm going to get a divider and put in so the sen can get some size to it and then take out the divider if the ycan co-exist, the bluegill is rather peacefull but I'm just worried about the bichir getting abused.
