Nemo is swimming funny

[boom215]

I bought two false percs. about 3 weeks ago. they are eating and look good, but when they are swimming around or just chilling on one spot, they seem to swim diagonaly. if you were looking directly at them they are like at a 45degree angle. is this normal? thanks

Are they doing this near where you released them?
Are they doing it near a powerhead?
Guess I'm not sure why they would both do it, I've never noticed any such pattern with my two false percs or ones at the store. Just give em the once over and look for any problems with their eyes, white spots on body or powdery look to them.
