Please help. Constipation? or Bloat? or internal parasite? or anything else?

I have recently decided to have a go at discus and bought x8 2-3inch from a local breeder. At first they weren't really eating the dry food for around 3 days so i switched to a wet mix which includes beef heart, spirulina, freeze dried whole Antarctic krill, garlic and egg yolk. They ate a lot and i feel i kind of over fed them if im being honest. Ever since their bellies seem really full and they weren't pooing at all. Sound around 3 days after the first feed i dosed epsom salt at 2 teaspoon per 10 gallons and they immediately started pooing in small brown pieces that would break off. The full bellies seem to affecting the blue discus more than the reds, although the reds do seem to have full bellies as well.

Im not quite sure what too make of this all or even if their is anything wrong at all. Ive attached some pictures of the fish for you guys to help me diagnose the situation.
