Its been posted on here before that you shouldn't keep most sunfish with Pickeral, the smaller sunfish will get eaten and the Largersunfish will usually attack the Pickeral. Redbreasts, Greens, and Dollar sunfish most of the time are aggressive sunnies and should be treated as such (there are exceptions to every rule); Bluegill, Pumpkinseeds, Spotted, and Longear are usually In the middle on aggressiveness and the majority of the time Bantam, Orangespots, Redear and Warmouth are not that aggressive to conspecifics in their own size group except Pikes and Pickerals who are a natural threat.
