A goldfish with a bulging belly may have eaten too much, may have ascites, or may be about to lay eggs. If the goldfish eats too much, it will cause indigestion, make its belly bulge, and it will often sink to the bottom of the tank. In severe cases, it will also appear Diarrhea. If the fish has ascites, this situation is often difficult to treat and can only be prevented by paying attention to feeding. If it is spawning, the eggs need to be removed in time to avoid contaminating the water quality.

Tip:

Goldfish is an omnivorous animal and can eat a variety of foods. Goldfish generally like to eat some small animals in the water, such as water fleas and other living creatures.
