My Discus has changed color from a bright beautiful blue to a deathly black and his eyes are shaded and glossy. He is the only male sharing a tank with 3 females.
What has caused this horrific change in color? How can I help my poor fellow?
Reply:
1. Your male is sick.
2. The eye probably attacked by fungus.
3. Give them Acriflavine and salt bath for a week.
4. During the treatment do not feed them. Unless you think they are ok.
