if that's a burn, then you need to be treating it most likely with Silvadene Cream. 1 percent includes 10mg of micronized silver sulfadiazine. with a burn, you need to be concern with the area becoming infected. take everything out of the tank and use paper towels and a water bowl. don't use the uth until you get the temps from it controlled. and I don't think I would even use it until this heals. the slightest heat on a burn = pain. silvadene cream is also used on humans for burns to prevent infections. keep the enclosure clean. very important. change the paper towels at least twice a day or more if needed.
