I think my kole tang had ich, it turn powder white and lost most of it purple color and started getting spots on it's fins, so I got my QT up to par to transfer it over and was ready to move the fish took another look and he is purple again and no spots. Is it possible that he recovered by itself or should I move it and med.??? Just thinking the move might stress him out and bring it back so I would gain anything. I did add a uv light right away once he lost his color, been running for 48hrs. Please give me your opinon what to do. Thanks Sorry no pic of fish when it was bad but could take one now and post if this would help.
