Can goldfish eat themselves to death?

Goldfish can be eaten to death. Because they have no sense of fullness, they generally eat as much as the owner gives, so the owner must control the amount and avoid feeding too much at once, or the fish may be overfed to death.

If a goldfish eats too much at once, the large amount of food piling in its intestines puts great pressure on its digestive system and can even kill it directly. The owner is advised to feed goldfish at fixed times and places, in small, frequent meals.
