Greedy for air.

Subject: Greedy for air.

I have two small goldfish in a tank with all the trimmings.

I have a problem goldfish. He (or she) floats. Now, I have noticed that the hungry blighter keeps eating air bubbles from the top of the tank and then forces the air bubble into it's body by swimming down vertically. I have even seen air bubbles in it's line of sh*t.

I wonder if I use a finer gravel that the fish can eat and use as a ballast to counter act the floating?
