Jeremy said:I think that the tank is too small for Discus, and they really need to be in groups of five or more.
Making them adjust to cooler temperatures isn't really ideal either, as the welfare of the fish should come first.
I know you must love your Discus but I would either get a larger tank, and a larger group of them or get rid of them.
The glosso doesn't really suit their feeding style either as they like to bounce food particles off the substrate, so a bare patch for feeding is best.
Don't think I'm just snapping away at you for fun, I'm not, but I've seen a lot of great Discus tanks over the years, and the big ones are always the best in terms of aesthetics and the best for the fish.

its currently running just two bulbs while i sort out my algae problems
