I think What I'll do is use two ceramic heat emitters placed at each end of the tank. It is not possible to heat the room as its in the basement and all its warmth comes from the heating of the ground floor. If the basement was 75 degrees, our main floor would be around 8o or 85, and that is too hot, costs too much, and isn't environmentally friendly. I don't see any point of making these guys warm but destroying the environment their wild cousins live in in the process. Kind of hypocritical. I think the ceramic heat emitter idea will work. Thanks.
