Ever since I bought my blue tang it has had the ich. It was the only fish I bought from a pet store I had never gone to or knew anything about it was like a little corner store. I've tried fresh water dipping three times now and every time the ich goes away and comes back. Today I finally decided to get a cleaner shrimp and all day long they have been side by side and the shrimp seems to be doing his job. Any tips or recommendations on getting rid of this parasite ? I hope this shrimp does the job.
