You haven't removed the dead one.
The other goldfish might be bullying - please remove the black one before it stresses too much and dies.
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.
Give it more fresh water feed it or it is so darn sick it just dies .......goodluck.
You can walk a dog, but you cant walk a goldfish.Goldfish are cheaper, and dies faster, so are easy to replace. A dog is a better companion then a goldfish. A dog eats and loops more. You don't need to clean a dog's tank.
Some common breeds of goldfish are: the Black Moor goldfish, the Ryunkin goldfish, the comet goldfish, the common goldfish, the Calico Fantail goldfish, the telescope eye goldfish, the bubble eye goldfish, the pearl scale goldfish and the Oranda goldfish.
