What are these black spots in the belly of my puffer fish?

[professorjimjam]

I went for 3 days vacation as it is the holiday season. I came back today and found that the male spotted Congo puffer has some black spots in his belly. I fed them earth worms and they ate them vigorously. I don’t see any sign of stress but I have never seen these kind of spots, they look outwardly and they are black color. I have taken some pictures and I hope someone can identify this here so that if it is some problem then I can act on it faster.
Appreciate your help

here are the photos

Might just be some dirt on it.
Keep an eye on him for any change in behavior, of the spots multiply, or if any other fish become infected.

I did that with my Congo puffer. Thought he had ich, but it was just sand stuck to him. He looks good! I wouldn’t worry unless things change.

Yeah was about to say, their slime coat is prone to stuff getting stuck to them, especially when they been laying on substrate...
