My blue hippo tang has what appears to be ich. He has tiny white spots on his fins and scales. The fish is still very active and is eating well. My tank is a 220 gallon reef and my water levels check out fine. I have 20 fish total and I do not see signs of ich on any of the others. I have read many post on here associated with this disease. Some say quarantine and some say not. I would prefer not to cause the fish the added stress of being caught and put in a quarantine tank but I do not want to risk losing my fish. I usually feed garlic soaked food to my fish every few days. The research that I have done shows this to be an effective preventative measure but not a cure. Has anyone had any success with the product called “No-Ich Marine” by Fish Vet? My tank is about a year old so I am still new to the hobby. Any advice on how to treat this fish and my tank would be appreciated. I have 20 fish so quarantining them all for 8-12 weeks is really not an option.
