Well, I have tried feeding him in and out of his enclosure, the same ones he has always fed in. He has been feeding in a separate enclosure since I have gotten him. I generally tried outside his enclosure.
I don't know why he just magically took it at the store, and not at home, I changed nothing, he ate in the same box as always, I thought the travel would stress him out, but did the exact opposite.
I will grab some construction paper and put it on his tank..
