Molly swimming in a strange way

[Hyzenthlay]

He's eating and it isn't constant. It comes and goes. But it's very strange. Dealing with bacterial bloom but water parameters are on point. Any ideas? Tried to upload video but I guess mp4 not accepted here. Don't know how to change it. So basically he swims vertically and his body looks like an S. Then he gains balance and back to normal.

Anyone else in the tank? My platy swam vertically in an S shape when it was showing dominance to another platy

yeah, he's definitely not alone. I have 3 other mollies, 2 cory cats, 1 otto and 1 loach. all boys.

you can upload a video to youtube and link to here.
mollies are prone to shimmying, harder water and even a little salt may help.

 

[Hyzenthlay]

so no cause for concern?

 

[qldmick]

maybe add some kind of limestone or coral gravel to your filter or tank, do a water change and hope for improvement.

I’d like a video, could rule out aggression easily that way. But typically there’d be another fish nearby that he was “shaking” towards if it’s aggression
