Mollie Swimming Vertically

[Fishy Mishy]

My Mollie seems to be swimming vertically - head up tail down.
She is eating and seems ok now however I have just finished treating her for whitespot
The whitespot has gone and I thought everything was ok now
The only other things I have noticed is my male mollie seems to be circlling her with his dorsal fin fully flared - although he has done this before and she has not started swimming vertically.
Any ideas?

does she shimmy? like she having a seizure? i had a couple mollies do that. they would look up and start shaking for a couple secs. then off to normal. they would do it every 10 mins or so. didnt find the problem, as they died. from something I did, not the shakes.

What are your current water params? What size tank? As it sounds like she might have swimbladder. You could try giving her a pea, she should eat that pretty willingly. Mollies like veggies.

Also, the male is trying to mate with her. He's showing off, and trying to impress her, which is normal. I doubt this would make her swim vertically.
