Please help!!! I have a recently setup a saltwater tank that will eventually become a reef tank. The tank was set up using dead rock and and sand, with the exception of 20 lbs. of live sand. The only two inhabitants of the tank are 2 clownfish. These fish have been in the tank since July 5th. This is the 2nd day that one them refuses to eat and I noticed 2 small white dots on his body behind his right fin today. I have tried to get pics or video of him but now he is barely visible hiding behind a rock structure. I don't understand how ich was introduced to the tank because these fish have gone through a full quarantine procedure in my hospital tank of cupramine and prazipro. My problem being, I have 2 more fish presently in the hospital tank that are in a full dose of copper right now and I only have the one hospital tank. Is there anything I can treat the clown with in the main display tank that is reef safe, or will have worn off by the time I introduce coral? Any advice is greatly appreciated.
