Female presenting to male?

[Cymberli]

I have a female molly who hangs vertically and I have noticed she only does this when there is a male nearby. Is this a mating behavior? Is she presenting herself to the male? She is healthy otherwise and so evidence of swim bladder...she only exhibits this behavior when a male is next to her.

Hmmm, it’s pretty odd must confess. Is it head up or down?

Heads up. I wish I could catch a picture...its almost like she is hovering there in place

On iPhone here but heads up I find a bit more reassuring. Only other thought was I wonder if a learned trick to stop/slow him.
