Aw that’s annoying sorry to hear that. I know how it is to see a coral unhealthy. I hope the best for you and your coral! What did you do with the peppermint shrimp?This just happened to me too. I bought a new teal frogspawn and some torches. The next morning, the frogspawn was destroyed by a shrimp. I pulled it and put it in my frag tank but I don't think it's going to make it.
