Goby Question

[thall17]

Don't remember this dark spot under his mouth...could of always been there but don't remember it...does it look normal?

Looks intense, like a burn. Looking at google pictures, some diamond Gobies have the same black spot and some don't so kinda hard to know if something is wrong.

Is the fish looking healthy ?

He seems fine, eating and sifting sand lol

I have the same diamond goby and this dark area is normal. I thought the same thing when I bought mine.
