Found this in my coral qt. Hard to get good pic, its very small, 1/8 inch or so. Came on a piece of rock I bought to put in coral qt. I dipped the rock before putting in. Its growing at a pretty good pace. I'm a beginner, so just being cautious. Any ideas? Thanks!
Ball anemone. Many consider to be a pest. I have a couple in my tank that don't seem to bother anyone and hasn't moved in the 3 years I've been reefing. But if you have it in qt now would be the time to take care of it. Scrape it off and super glue over where it was to prevent it from coming back.
