White spot on black goldfish head
I'm not sure if these black goldfish have the white spot on their head normally. But now I saw it after couple days I brought then home.
Please see the attached picture. It is kind of hard to see, but I circle it, so it us easier to see.
Is it normal for these black goldfishes to have the white spot on their head. I have 2 black goldfish, but the other one with the lighter white spot on their head.
