HICCUP!

[Abbi]

I took Tang out of the tank one day and he did something weird, what seemed like he was hiccupping? But with no sound. He seemed fine, and after a while he stopped. Anyone know what this is?

Can't say I've ever heard of this before. Sometimes after feeding, a snake will open it's mouth and re align it's jaw. But this is totally different from the hiccupping you describe.
Good luck.

I see mine slightly jerk back a few times like a hiccup but it stop. Nothing bad.
