False Perc not moving

[robertmun]

I recently got a new tank-raised false perc. I noticed that when the lights are on, he doesn't move much - just stays in one spot near the surface.

 

When I turn the main lights off, and turn on my moon light, he swims all over the place and hangs out with my other, larger false perc. He eats when I feed, but otherwise, when the lights are on, it seems he's sick.

 

Any thoughts?

I've seen my percs do this. He'll just swim near the top in a corner for long periods of time. He died of some infection a few days later. I'd keep an eye on him he may be sick.
