i got Rocky, 10 mo old male 2 weeks ago yesterday. he had sand in his tank, so i covered it with a good layer of paper towels till i can get it out of there...hard to get him out for any length of time so i can pull maintenance so to speak, till i get him tamed better. anywho, past 2 days he is digging and digging....this morning i got up, turned lights on and he woke up and started digging like crazy. also seems to have more of an appetite? what's this digging all of a sudden, or is it because he is more used to surroundings now? HELP! changes in his behavior make me nervous lol
