Ive had that coral for a little over a year. Beside peppermint shrimp, what else could eat coral that fast?

I have seen hermits do that to one of my favia and had to throw him in another tank.

Something ate it, watch and see. My hermits picked the F out of one of my leptos. We about had crab for dinner.

yeah I know , I stooped using any Phos remover and Im feeding more. trying to slowly raise it. I have quite a bit of algae growing so I think its just getting used up quickly.
