Is this normal? or is something wrong?

Tonight my ax started doing this sudden jerking upward jump, almost like an involuntary spasm. Since I'm new to him/her I have no idea what to expect. However he's never done this before, just started tonight. I took video of him doing it. I couldn't figure out how to post it here so I uploaded it to youtube, hope I can put a link to it here.


What's up with my Axolotl - YouTube

He's just eating. When they eat they use a vacuum like suction and it caused them to jump back sometimes.

Yup, just eating. It's adorable. My leucistic used to get super exited at feeding time when she/he was little and she'd jump really high and then look around like "huh what was that!? ".

I miss when mine used to do that, back when they were on a bare bottom and I could let them just suck the food right off the ground.
They are ridiculous little creatures.
