Is a goldfish a vertebral?

There ancestors are gold... different colored traits over time dominated the classic gold color, while in some breeds, the gold color will dominate during the trait selecting process

Nope! Black Moors and other black goldfish get along fine with almost any sort of fancy goldfish.

Because it will be matingg season for your goldfish'swich means one of them is a boy and the other a girl.the girl will be the one with the mostly wided V tail, butremember goldfish lay from 15-20...

Goldfish are a form of carp. They don't eat other goldfish, but they eat small flies. Sometimes goldfish like to eat tiny tropical critters such as ghost shrimp, but they don't eat other goldfish...
