I just added two new marroon clownfish and about a day later the larger of the pair developed a white spot on the right side of it's mouth it doesn't look like the descriptions I've heard of Ich but I bought a bottle of Kick_Ich in case. This morning it seems to be slightly larger than when I saw it yesterday but the clownfish still seems to be in no distress. I tried taking pictures but none are good enough to add any more than my description (small raised white spot on right side of mouth) looks like a pimple really. Please help me diagnose this fast and any tips on how to treat. If there is a way to treat in the main tank that would be the best. I have a reef tank with small amount of coral, a few anemones and a clean up crew with hermits, snails, shrimp, starfish etc . . .. The other fish are Yellow Tang, 2 Banggai Cardinalfish, firefish goby and smaller marroon clown. As of now everything still appears normal and happy.
