I truly appreciate everyone trying to help by telling me they have parasites, but I can tell you there is no way the clowns and my blenny have Brooklynella. How on earth would they have gotten it after all this time? The clowns were ORA captive bred, too. I really have tried my absolute best to explain the way this occurred -- it was a freak, scary occurrence that lasted for a few minutes until I turned off the pump. Ever since, all fish have been fine. At no point did any fish lose their appetite or refuse food, or show any odd signs like stringy poo, etc, before, during, or after the episode. It was like nothing I've seen before and I'm really baffled by it. Just took a chance posting here hoping someone might have some insight or would be able to brainstorm some troubleshooting other than telling me the fish have parasites TBH.I suggested the electrical tester as I know how it is to have a gut feel and wanting to "just know" and check it off the list if its not. I'm thinking a parasite as I'm going through a similar thing with my clowns and have one in quarantine because of it as we speak. Brook although I know in my experience is sneaky at first. The outside will look fine yet the fishes insides have things going on. Then the progression you see the shift and its clearly noticeable on the outside. Just been my experience.
