powder blue needs help

[blue steel]

I have a powder blue and he will keep his mouth wide open. I thought he may close it when he eats, but he did not. He could not even eat due to this. I feel there is somthing major wrong with him. the only other thing I have noticed is that he has a few black spots only on his vental fin.

Is this a new addition? Can you post up a pic?
