Goldfish eggs are extremely small in size. A goldfish can lay several hundred eggs at any one time. If an egg is fertilized it will be transparent. The non-fertilized eggs, on the other hand, should be white in color. If any of the eggs catch fungus they may turn green or blue.

Goldfish produce adhesive eggs that attach themselves to aquatic vegetation. Typically this vegetation will be a dense plant such as a Cabomba or Elodea. The eggs will hatch within 48 to 72 hours. The New World Encyclopedia describes the fry released from the egg as being "large enough to be described as appearing like an eyelash with two eyeballs." Within about a week, the fry will begin to look more like a goldfish in shape. However it can take as long as a year until they develop a mature goldfish color.

The goldfish is a freshwater fish that belongs to the Cyprinidae family of order Cypriniformes. It was one of the first types of fish to be domesticated and continues to be one of the most commonly kept aquarium fish. Goldfish are a domesticated version of a less-colorful carp, which is native to East Asia. The goldfish was first domesticated in China over a thousand years ago. Goldfish breeds vary greatly in size, body shape, fin configuration, pattern and color. There are a number of combinations of white, yellow, orange, red, brown, and black that goldfish are known to have.

Hey are pretty much the size of the air bubble. They are white with a black dot. The yellow ones are dead thou. I had some in my tank but my goldfish ate most of them so it is important to either remove your fish or the egg out the tank or they will get eaten. Also when they do hatch do not feed them for the frist 24 yrs as they will be eating thier own sack and food will just dirty the water more. If your eggs are in a tank rather than a pond feed them liquidfry. X

Common goldfish eggs are of very small size. A goldfish normally lays hundreds or thousands of eggs at a time. Normal fertilized eggs are transparent and the non-fertilized ones are white. Some of them might catch fungus and turn into some other greenish or bluish color. The eggs normally get stuck on the leaves. So I think that might be eggs that you have seen glued to the leaves.

My goldfish has eggs on the plants in my tank, they are white with a black dot in the middle. Before my goldfish laid the eggs they always chased each other aroun,  and about a month later I found eggs on my plants. At the moment, there are about 200 eggs in my 25 gal tank. However, most of them might not hatch or get eaten.
