I have 2 Red Melon Discus around 5 inches that have stopped eating. It’s been going on now for about 3 weeks now. I can see them starting to get skinny. One of them is starting to breathe a little heavy. They were in a 90 gallon with 7 other Discus that range in size 4 to 6 inches.That tank has 2 AC110s and an FX5 canister filtering it. Tank also has about an inch of gravel. I change water 50% two times a week. I put them in a 55 gallon tank a week ago by themselves, and raised their temperature of the water to 92 degrees. That tank has a bare bottom tank with 2 AC110 filtering it. Wondering if there is some medicine or epson salt I can give them?
