Possible Sick Fish?

    I have a small school of Pristella Tetras. Over the last month or so, one of them looks as though his belly is filling with something. It started out mostly white, but now has transitioned to mostly black, with the white being pushed toward the tail. I’ve looked up common fish illnesses with no luck. He seems to for the most part stick be acting fine. Any ideas of what this could be?

    Could be a bacteria infection or possibly ammonia burn. What’s the parameters?
