White Spots on Juvenile Blue Tang

[goriogabriel]

Hi! Hoping someone can help me identify these white spots and scratches on my blue hippo tang.

i got him a month ago with white fades on his belly and i notice the scratches and spots continue to multiply. He also loves to scratch his skin on live rocks and would constantly fit himself in small openings of the rocks

His diet, breathing, and swimming looks normal. what could be the disease and how do i treat them?
I’m currently using Seachem supplements. No medication yet.
