my substrate is 1/2 crushed coral (i've since learned its bad) and the opposite half is sand. Well, my purple w/ yellow tail damsel has been digging out the crushed, picking up the pieces one at a time and moving them about 6" away making a pile. He has been doing this for a few days, and has probably dug out a 2" hole, is this typical? what is he/she doing?
