i just got a 10 foot burm and his face looks odd, his upper jaw and nose area seems blackened he also hisses oddly and usually has some bubbles in his mouth. sometimes when he breathes it soundes gurgly. i dont know what, if anything is wrong with him. i was planning on putting him in the cage with my other 10 footer but i am hesitant because of this problem, i dont want it to hurt or infect the other snakes. also he was very docile when i got him. i tried to feed him once since then but he did not eat. now he is fairly hostile and strikes at me when i clean the cage, i have been carefull with him and thusfar have not been injured but i would like to know what is wrong. thanks alot for your help
