How do goldfish have babies?

Answer by  Tank (539)

Goldfish lay eggs in a sticky group called clutches. These clutches will hold to a plant or aquarium decoration. In order to simulate spring time in the aquarium, change the water weekly as well as increase the diet. The diet should include meaty or frozen food as well as flake food.

The female goldfish will lay the eggs. The male goldfish will fertilize the eggs. Then after they'll just let the eggs fend for themselves.

I believe that they lay eggs like most other fish. Females lay their eggs while the males do their "thing".
