Axolotl hiccup? Is she ok!?!?

[Aztec the axolotl]

Ok I have just fed my axolotl and it looks like she is hiccuping. Do they do this!?!?
She would"hiccup" and float upwards a Little. She ate 3 pellets and then started doing it. She seems fine now but I'm terrified she's not ok.

i’ve found mine hiccup whenever they’re distressed, does she blow bubbles?

Not really , I've never really seen her blow bubbles but she blew a few when she was hiccuping
