Is my fish sick?

[NEVERLAND]

I have a silver molly and every now and then. Actually multiple times in an hour i see her doing something weird.

Basically i see her face up. Like she makes her body up and down straight like a line. Head skyward and tail to the bottom of the tank. And then if you look closely she starts to twitch. It starts at her head then there is a really violent twitch of her tail and she seems to go back to normal.

Is my fish sick or is it just a weird fish?

Are there any other mollies in the tank (male/female)? Could be breeding behaviour.

So the shaking could be mating behaviour. I would up the frequency of water changes, vacuum substrate, and keep observing.
