Platy with swollen belly. He's a food hog..

Platy on the right.. He has been hogging food every time I feed the fish. He is with 11 other platies, 5 like him and 6 yellows.. He must eat a quarter of the total.

Do you have any idea what could be up with him?

Can't see the picture.

What are your water parameters? Tank size? What do you feed?
