Answer 1

Read this article and see the website.  This isn't a serious problem.

Does your goldfish blow bubbles after it eats? Is it a "floater," drifting cork-like to the surface after meals? Do you see goldfish excreta with bubbles attached floating at the water's surface? If any of these symptoms sound familiar, then your goldfish is probably suffering from...goldfish gas!

Gas and constipation are the most common digestive upsets in gold fish. The fancy short-bodied breeds are most susceptible because their internal organs are unnaturally crowded together. In orandas, constipation often causes the stomach to press on the swim bladder, interfering with the fish's equilibrium. "The goldfish's stomach has a higher pH than the stomach of a meat-eater it's not nearly as acidic. The only animal proteins a goldfish seems to digest easily are earthworms and bloodworms. Keep them away from beef heart."

Your goldfish's greedy manners also work against him in matters of digestion. Goldfish gulp their food ravenously and may swallow air along with it. For this reason, the GFSA recommends that you feed sinking rather than floating pellets.
