Raise his hotspot to 90 degrees and put him in a smaller tub. That's a pretty big tub for such a little baby. Also feeding on the same day they shed... its a 50/50 chance they take it. Best thing to do would be to get his hotspot raised up and with a smaller environment (such as a 6qt or 12qt tub)... then leave him be for a few days and then attempt to feed him a hopper again. Bet he takes it
Wow, yea I totally missed that part of the post as it didn't load on my cell phone. I keep some of my hatchlings in 28 qts but I have a million hides so it's a crammed floor space.
