OK, hoping for updated input.I ripped apart my display tank and finally caught that super fast, amazingly evasive little flame angel (Wow, can that guy move!). I was pretty sure that the most likely problem was ich so I put him into a hospital tank with Cupramine. Within about 3 days his single little white spot on his pectoral fin disappeared . . . and a single white spot appeared above his eye. Approximately 3 days latter the spot above his eye was gone and a single white spot appeared on his side about a quarter inch back from the base of the pectoral fin. It is tiny and impossible to get a picture of (believe me I've tried)! At this point, it is only visible from certain angles and you would never see it if you were buying the fish. The spot sticks out from his body but is a very distinct round spot. It does not appear cottony or irregular. It is a tiny, perfectly round, white dot that protrudes from his body. He eats 4 times a day garlic and vitamin soaked mysis, brine, sponge, nori, etc... nothing wrong with his appetite. He is not acting sick in any way. To clarify, I did not get this fish from any club sponsors. All the fish in the main display are super health and there are no white spots on any of them. If I were not looking so carefully at the flame, I would say he was completely healthy. What the heck is on my fish and how do I cure it?
