I have three emperors that have been swimming weird all day. They kind of “bounce” up and down in a vertical position, nose up.

I took a video of them
They aren’t gasping at the surface, and when it’s feeding time, or another fish chases them they are able to swim normally.

My ammonia level is zero, nitrites are zero, nitrates are around 5. Water temp is 24 celcius.

Could it be a swim bladder problem?
