Update-I had a gut feeling that if I moved him into my rack, he'd eat. I moved him into it 2 days ago and today I put a pinky in one of his hides with him. (they are the medium sized hides from rbi, so it wasn't shoved in his face.) 30 minutes later he was out and about so I grabbed the pinky and heated it back up, when I came back he was in the other hide, so I just put the pinky right in front of the hide. 15 minutes later and it's gone! I'm so relieved, it's been over a month and I was getting worried.

The tub was a 41 quart tub. I had a small fake vine in it but he chose the rbi hides instead. I guess I'm just saying that puting hatchlings in a big tub and having hides that are really big may not be that important. It took the exchange from a 5 gallon tank to a 41 quart tub to get my 7 gram hatchling to eat.
