Somehow my Grouper caught Flukes. Maybe corals from private sellers. Secondhand live rock. Anyway at first I thought he was scratching microbubbles off from the skimmer. But then he started going near the top. And having labored breathing. I did a few freshwater dips with water from a cichlid tank to match ph. That showed flukes in the bucket. I have tried treating the entire tank with prazi pro. Not much success. I even shut off the skimmer. Next I tried Hydroplex dip. That seemed to help. Then I tried Rally pro in the tank but lost some inverts. So stopped. He hasn't eaten since the last Hydroplex saltwater dip with all three fish. For about three days. Today I took him ount and dipped him with Hydroplex 10 minute saltwatr dip. Then I put him into quarantine with Cupramine. Online Cupramine is said not to help flukes but the bottle says it does. I am hoping to help him. I can't freshwater dip him because I don't have a way to raise the ph. I was getting water from fish store for the dips. Any help would be welcome. Also when in the dip bucket several days ago with the Triggers I think they bit him. Part of his fin is missing a chunk and he had a red bloch on his side. Normally they do not bite him. But thought I'd mention it.
