As you may have seen in another thread with pics, I recently acquired some discus. I've been keeping them at about 86 degrees, but a local breeder I got a few of them from said it needs to be at 89 - nothing less. I know discus love warm water, but is that warm really necessary? I think I've read for breeding the water should be warmer like that.... Anyway, I want to make sure I have them at the right temp, so what temp do you keep yours at?
