I have just found an Eel living in once of my pieces of live rock. Since i have not added any rock for a couple of years i have to assume he hitchhiked on on one of these as a baby. The thing is he never comes out of the rock (that i have noticed so far). he just pops his head out. I shined a light into his den and he took off deep inside it but i could see that he was 3 or 4 inches long. Looked kind of red in color. (need to figure out how to get a better look).
He also seems to cover the entrance to his den with sand every night or so. Then its open the next day.
Any thought on how i can identify him? or feed him?
