Be had him for two weeks an he was doing good but one of my HQi lights burned out an it took a week to get the new bulb here. He stayed under the one good light for awhile then he went on the move. He isn't opening up anymore like he used to (he is normally almost 12" around) and he won't eat now. I have the new bulb in an he finally settled into one spot between the two lamps. He attached to the live rock instead of burying in the sand like usual. Should I just leave him alone an see if the new lights help him get stronger ? Is there anything else I should do?
