Hey guys, on my blue spot toby, he has an identical black spot on both sides of his body, on pretty much the exact same spot. Is this disease or is this normal for puffers? Thanks. I was thinking it was disease at first but the fact that he has an identical-looking spot on the exact opposite side of his body makes me feel like that's just him. He acts completely normal in my opinion and eats fine, but if this is a disease I want to get rid of it asap because these black dots mess with his appearence.
