I recently cured two discus (one male and probably one female) from HITH and some weeks ago I put them back at the main tank with the other 3 discus. At the beggining both of them look very good, till last week when the female stopped eating. She is at her colours but she refuses to eat. I do my best to make her eat but nothing. At her best to eat one or two bites, but thats very rare. Also the only discus that lets to be next to her is her mate from the quarantine tank. Im really worried and I dont know what to do. Also she is the one that has the heavier breathing of them all.
