Tetra Advice

[Dukefish]

So I have some cardinal tetras in and among st my betta sorority. I have noticed that one of the female tetras seems to be swimming erratically.

It maintains a 30 degree angle (headfirst) and kinda swims by pulsates up and down the tank.

None of my others are exhibiting this behavior, and swim about normally.

She still eats and has no blemishes or marks on her body. I can't see any fin damage or anything either but its noticeable compared to her other tetra buddies.

Any thoughts, input or advice would be most welcome!

What is your tank stockings?

betta should not be kept with other fishes as they are territorial, aggressive and a fighter.

remove all of betta or other fishes to a plastic tub asap before betta gets them all.

Betta sororities are made up of females. And if the tank is large enough and well planted a community can work.
