I've never known a clownfish to burrow, but my maroon clown has dug itself and path underneath my live rock. At first I though it was doing it just to make a path through the rock, but every day it keeps digging deeper and deeper. Today I even saw it pickup a rock, swim out of the burrow, then dump the rock away from the hole its been digging. Usually it just moves it tail back and forth real fast to stir up the sand.
This clown doesn't have a mate and I don't have an anemone for it, so any clue on why it keeps digging away underneath my rock?
Below are some pics of the burrow.
