Female Hongloi sick ?

[tat]

Hello,

I have a pair of Hongsloi, on a 20G tank.
I have noticed that the female can't keep the equilibrium when swimming. I don't know what the problem is, but she does not have other visible signs of sickness.
The fishes arrived to my tank 40/50 days ago. I don't know if she was swimming this way from the beginning, I only noticed 2 weeks ago.

Can anyone take a look on the video below?

Thanks

First, welcome to the apisto forum. No, your female appears to be just fine. What you are seeing is typical apisto behavior. If the female wants to avoid aggression from an over-amorous male, she will lay over and display her flank to the male. It is often seen as a part of the courtship ritual that occurs prior to spawning.
