How Big Do Goldfish Get Before Spawning, How Many Eggs They Lay at a Time, and a Detailed Guide to Raising Them
Goldfish are the earliest breed in the history of ornamental fish in the world. They are easy to keep, have unusual shapes and brilliant colors, and are generally golden yellow.

Goldfish can spawn multiple times during the breeding season. In the places reached by the light, small fish will hatch in about a week.
