Hi all, I noticed today that my Plakat Betta on his side has some whiteness to his scales and they also look bent. I was wondering what people think this could be. Pictures are below. to me it looks like he maybe scratched his side? There is one large rock in the tank that he could have scratched himself against, what do you guys think? He is in a 10 gallon with two Harlequin Rasboras and a mystery snail. Also, I tested the water and it is fine.
