Unfortunately, it looks Ike ich. Here's a good article to get you in the right direction. Freshwater Ich? Yuck! - Aquarium Advice
What are your current parameters in the tank ? When was this added and where'd it come from ? Did you QT first ? What's the tank size and stock ?

Nitrates are 20. No nitrites /ammonia. Ph is 6.8, fish shop has a breeder that had received them from hans Germany, and then breeds them here. 84degrees. Fish was added a week and a half ago, 55 with 30 cardinal tetras, planted tank. Its a dark angel discus i believe
No qt, we personally knew the guy who we got em from and he had him for quiet a while. Probably should have. we do the water changes every 3-4 days. so today we are supposed to do one, but is it okay to do with the discus in the condition its in? We only have the one, around 2.5-3 inches in size. Got caught up with home life, were planning on grouping them
Would he do better in a group now? Or to wait to see if he gets better is the best route?
