My friend has a 55gal. Reef and has found ich on her green clown gobby. She has seen one spot on her scopa tang as well. What can she use besides garlic to treat her fish. She can't get the fish out of the tank without taking all the live rock out. She has inverts in the tank and can't use a lot of the traditional meds. Can someone please give me some info to pass on to her. I would do it myself but I am a little on the busy side to do a lot of research. Thanks everyone.
