Pic? Water parameters? Is it leaning towards a brighter light (sunlight) than the tank light? Is it feeding? Need some help here to understand what's going on.

Cannot see a pic however Black piranhas do tend to lean to one side and often swim that way too, especially when they are young.
My 7 inch black did that when I first got him at 4 inches and now he no loner leans.
