My juvenile peacock bass has skmetsome up with him but not sure what. His fins are all scrunched up, hasn't been eating and has almost a white film on him. All other fish are perfectly fine. Water is spot on, I 20% wc every 3-5 days, nitrates and nitrites are fine, no amonia, pH is good, just don't get it. Only thing I can think of is some type of fungal infection. Should be noted I do not feed live, he accepts beefheart l, shrimp, and blood worms.
