being paranoid or a bigger problem?

Yesterday morning my bumble was at the front of his tub exploring when I saw him lift his head up and kind of roll it backwards upside down towards one of the airholes and stare at me. I pullled the tub and he put it back forwards and went on his merry way to the back of the tub.

Later that night the Mojave girl above him did the exact same thing. Put her head back and stare at me for a few seconds until I touched her tub. She then went straight to her nearest hide.

The bumble as well as all my other Snakes ate last night. The Mojave hasn't eaten in like 4 weeks but the last 2 meals were huge and she hasn't lost a gram.

I hear all these horror stories about ibd and it makes me nervous. I don't see any other symptoms though and their heads were that way for 2 seconds each. Has anyone seen a ball do this before? They both are very alert and tthe Mojave has the aim to strike at me like she's always done. I've seen videos of ibd Snakes and they are doing crazy stuff.

Other than that 2-3 second period each they seem normal.

If they are just exploring, I wouldn't worry. There are a lot of symptoms for IBD and I don't believe looking up the side of the tub is necessarily a symptom. Mine climb their sides too, and will freeze if they see me walk up to them lol.

Yes, it is normal behavior. There just being snakes. My granite yellow anacondas do that and other weird neck movement's. Because there probably wanting to get out or want me to feed them,lol.

Many of the IBD videos are not IBD videos.

One of the most (in)famous was of a snake with bacterial meningitis.

Your snakes are fine.
