I just dont know what to do:(

I agree with the 6 qt tub, they can be purchased very cheap at walmart. How much does he weigh?

Honestly you are lucky the others are eating in 20L's. Hatchlings should be kept in much smaller tubs, personally I don't use 6qt tubs, I use hatchling tubs from Vision Products. 6qts will work just as good and are much cheaper. The reason for the small tub is security to the animal. I would also suggest moving him to a 6qt tub, temps in the upper 80's to 90, aspen or paper towel as substrate, and NO HANDELING for 7-10 days. Then offer a live mouse a little smaller than the biggest part of the snakes body. Good luck with him.

Thank you every one i will go get a smaller tub and put him the spare bed room.

Melissa, I'm so sorry to hear that your little guy is having so much trouble and I know it must be hard/frustrating watching him like this. I would deff. get him checked out by a herp vet to see if the physical injury can be corrected to where he can consume his mice; if correction is not possible sadly I would recomend putting him down over just letting him starve, it seems to be a more humane action for the snake. I hope it dosen't get to that point and I wish you and the lil guy the best
