sick discus

[bengy]

I recently put two discus in my 150 gallon tank and after 2-3 days they have started to turn almost black and lethargic. i have treated with salt in the water and also with some ick/all around anti-badness medicine. the eat blood worms but they are still black and not as active as they should be. please help!

Hi
Discus turn black when there less than happy with something but there can be a multitude of reasons for this. How is the tank decorated. have you checked temperature and pH. Anythign that migth stress them.

Yeah the tank parameters have all been prefect until ii did a salt bath and some medication and the ph went up a little but they have been black for at least a week. the tank has a large piece of driftwood anchored to the bottom and like a greek collum thing and a few sword plants.

also he is starting to swim eratically occasionally but when i get close to the tank and he sees me he goes back to being his normal color and swims normally and looks fine
