What's wrong near this snake?
i was holding a sunbeam in a pet shop and i noticed as it moved its commander, sometimes you would feel a very tiny click from its neck, its impeccably healthy and moves around fine(from visual looks) but what do you think would be wrong near it?
It could have a neck problem or locked joint, I would advise you to take it to a vet or experienced breeder.
It's possible the snake was surrounded by blue...or had just cleared before it is due to shed. The dry skin can click and create odd noises when it's like that. Once they shed, they normally stop making the noise. If you're concerned though, don't buy it.
Answers: It could just be it's joints moving around after resting, snake's joints can 'pop' basically like ours can, but if you were thinking approximately buying and are concerned about it you probably shouldn't get it.
