I had a female red devil it's tricky getting my water temp to stay between 73-79 my room gets hot I'm talking about you can feel the heat on the window glass it's annoying. Even my tank gets hot. But that's what I walked into a hot room, water level dropping, and 85 degree tank. I'm thinking of moving the tank next against a wall. So I can prevent this in the winter cause that's when my room is icy cold.
