Hi
I recently bought a piece of live rock and found on it a piece of what looks like cunjevoi. here are a picture of it it not that clear but i can describe it abit. it is brown in colour and opens and close its mouth. its mouth is mainly open all the time.
My question is should i keep it on my rock or get rid of it.
