It depends on the conditions. If all the goldfish were being starved (for example) most of them WOULD die. But if one just happened to die for no particular reason, then it probably won't affect the rest.
Dispose of it.

The size of a goldfish tank can affect the growth of the goldfish. A larger tank provides more space for the goldfish to swim and grow, leading to healthier and potentially larger fish. In contrast, a smaller tank can restrict the fish's movement and growth, potentially stunting their development.
it either grows to be fat or dies.......i think
yes, it will
