yeah right now I have it set at 87, plus 3 pretty good sized airstones. Idk, I was just thinking about tank mates and wondered about Jack Dempseys. I dont want to get my bass or any other fish tore up, so I think Ill hold up on adding any fish. Pbass are by far the coolest fish Ive ever had, so it wont break my heart to keep them in a species only tank
