I have a red devil in with longear sunfish and green sunfish in a well filtered 125g. Tank is around 75-76 degrees and the devil is nicely colored and feeding well so the temp doesnt seem to be bothering him. (didnt buy him....was given to me and i gave him what housing i had) My question is if I keep the temp high enough are sunfish hardy enough to live with him? There's 8 long ear and one greensunfish and some others but there being moved monday.
