ok so i just got this guy in a week ago and put him in his new enclosure.
ate one meal, and is very active.
i took him out to show off to my bro and this was on his belly!!
i checked the substrate and he didnt burrow so its not a belly burn. its a glass tank so i do worry it will happen sometime but my other balls dont borrow so i hope he wont.
and i have felt the substrate and its not burning hot just warm on top.
i think one of his hides is too harsh, its like a stone texture. maybe he just scrubs against it to hard?
