ok so i put a good amount of cypress mulch in the bottom of the aquarium my little guy is in and what does he do but immediately bury himself. now this morning i unburied him and had him out for awhile but he did not eat anything and when i put him back in his cage to eat he buried himself again. should i trust that he will come out when hes hungry, or should i continue to unbury him and offer him food? its not like hes starving by any means but ya i worry bout the little guy
