Yeah, my 200's heated and at about 75 degrees. Those fish in there aren't long term because my dad wanted to put the local river lake fish in there because he never had them. But after 4 months of maintenence, (feeding and cleaning them) it became tiring. BTW they eat 7 dozen large feeders every 3 days. Which gets kinda annoying. Plus at the petland near me they have 3 big tanks that go on the floor at about 1000 gallons each. So I think they can spare the room.
