snakes tongue does not come out

Question
Hi.  I have two albino Burmese pythons about 700mm long one female and one male.  They both seem pretty healthy.  Tank has a heater mat with an electronic thermostat set on 28 degrees C.    Not sure on the humidity but do have a fair size water bowl inside the tank.  Now the problem is the one snake, I have never seen his tongue come out?  Since I got him (her) in December.  And he wont eat either.  Tried mice and rats.  He is not interested.  Now I have read that if a snake puts his tongue out all the time it is a sign of good health?  Must I take him to the vet or what?

Answer
Hello Peterjon,

I would indeed bring him to the Vet. Snakes taste the environment with their tongue. This is how the sense what is going on around them. When a snake does not do this especially after being held for a few minutes, it is discerning.
