His mouth sure isn't right...& right now I'd say it's more likely an R.I. or mouth infection -his mouth isn't closing right, possibly because he's been pushing with his
nose to clear his breathing, but more likely due to a problem inside his mouth, sorry to say.
Have you researched a good herp vet nearby? (or do you already have one?)
