I came home tonight to see my bicolor angel covered with white spots. The other fish look fine, for now. I have only 1 tank set up right now, and don't have much extra water laying around. Anything you can suggest I do? It is in a 46 gallon reef with 3 other fish, and they seem to be doing fine. I have a small 10 gallon I could set up tommorrow for it, and treat it in that. The only filter I have for it is a whisper power filter. Just pull the carbon out? Otherwise, I'm stuck with pulling the fish out and putting it out of misery. Let me know what you would do.
