That's actually the bedding from the superworms so no not sores but I feel like I may have caused it. He had this but a little smaller before and one time I was cleaning his mouth and a little bleeding occurred, no more than a needlepoint of blood so I wasn't too worried. Could have contributed. Not sure tough don't want to jump to conclusions, is it necessary to treat this or should I monitor for a bit and see if it gets worse or he becomes increasingly lethargic because at this point his appetite isn't too bad, he doesn't eat too many super worms but he'll eat a few and then go run around and such.
Thanks for the help thus far.
