Picked this up a few days ago at lfs. They said it is a favia but it does not look like one to me. It is very flat and hard with no soft flesh like an acan or brain.
This morning the crab in my tank was sitting on top of it and it looked like it chipped a piece off The area facing forward used to have a more round look to it. I don't think it was in the best shape when I got it but now its looking worse
Any advice?
