Once again my LFS has given me a surprise. This time my new mushroom 'rock' opened. Upon further inspection it seems as if the 'rock' is an oyster or bivalve of some sort. Indeed, this is 'live rock.'
It's egg-shaped, about 2.5 inches and the shell, though covered with algea, is striated.
Any ideas?
I assume it isn't harmful and will just filter the water?
Thanks in advance.
