I have neons, guppies, cories and a betta. Thanks!
Your water temp can go a bit higher, but 83 to 84 degrees would be the high end. Aquatic plants, if you have them, don't generally like water that gets too warm.
When the room gets a bit warm, I set up a small fan and aim it toward the tank. This is all it takes to drop the water temp a couple of degrees and maintain it. You don't need to adjust anything on the tank.
