Is it common to have things living in your favia? When I bought it over a year ago, it seem to have a tiny hole in it. I never thought too much of it, just figured it was one of mother natures defects. Well the hole has enlarged just a bit since then. I was looking at it really closely the other day and I saw a little critter face staring back at me. I would have snapped a picture but I think it is too small to show up. Anyway, I didn't know if it was common to have stuff bore into favia and live there?
