Thanks for reaching out about Tennessee and including photos. If he can not open his mouth, he needs to see a veterinarian, the sooner the better. Concerns are an oral obstruction, fractured mandible or other problems. Check and correct water quality as pristine water parameters will be needed after a veterinary visit. Good luck.
