Hi I'm new to discus and I have two everything has been fine so far until today I noticed that one of them is kinda hiding in the back and didn't eat this evening it's been only like 8 hrs since he hasn't eaten but if there is a problem I'm trying to stay on top of it. I have a 75gal. well planted tank with drift wood. My blue diamond is doing just fine really perky but my red Peguon is the one hiding what do you guys think it is?? Or is it just nothing??
