It's like a kind of jerky swimming movements without going anywhere. His eyes are cloudy, but almost looks like it in the process of forming a kind of haze they could be. Moreover, it seems quite normal.

I have kept fish for over a year and never treated. I tried to think to find the symptoms of the line, but I could be a quick suggestion for your problem here.

I have not made major changes in the reservoir, the temperature remains constant, the values within normal limits, the water is crystal filters and basic cleaning is always done in a reasonable manner. Added any new aquarium (with the exception of a new batch of swordtail fry) in the network of the breeder.
