He wouldnt even come out of his cave during the day when food was in the water.I would either have to feed him at night or put the food directly into his cave. Fed him earth worms and chopped fish/shrimp. Note: watch out for the spines on these little buggers, while they arnt dangerous, it still hurts quite a bit when they stick you. Usually throbs for about an hour.".
