Thanks
I just read a few posts and some people suggested that it might not be eating the coral itself, but eating any dying tissue or food on the coral. Just strange how it took off an entire tenticle, I think it just spat it out as I saw the green tenticle floating around the tank. I believe this happened overnight yesterday or earlier today too, before this just happened, earlier I saw an annoyed head of frogspawn and a peice lf tenticle on the rock next to it, and just happened again, hence the forum post
Hopefully its my decreased, now increased feeding, or its going after food on the coral
Some also suggested that peppermints are fully reef safe, and that it's camel shrimps that aren't, mine looks like a peppermint over camel, so I'll just have to see...
If this carries on, what would you suggest I do with him? I have an all in one nano, so no external sump, just filtration section
