Golden SAE Question - Help Please

I have a Golden Siamese Algae Eater & its belly is blown up like a ball. Looks like he has eaten a lot of food. I have had the fish for about 1 1/2 years.

On a side note - This happened once before with the same fish. Its belly got really big & round, then one day it was back to normal.

Any ideas????
