One of my gold fish lays lots of eggs and how can i hatch themthanks

I've already transfer the parents to the other tank and left all the eggs on another one - what should I do next?thanks

You should remove the eggs immediately and rinse them in a bucket of aged water that is the same temperature as the tank they were removed from. Your goldfish eggs should be kept in water that is not deeper than 6 inches. In deeper water the pressure can damage the fry and make it hard for them to reach the surface. After rinsing the eggs place them in a 20 gallon tank. You should raise the temperature to about 700F. The fish will hatch in 3-4 days. By the end of the first day you will notice that some eggs are clear tan to yellow while some are white. The ones that appear almost clear are the ones that are fertile. The others are more than likely infertile and will be subject to fungus. The fungused eggs should be removed immediately, or the fungus can spread to kill the other eggs.

Some breeders add a few drops of methylene blue to the water to cut down on the fungus occurence.

The fish will hatch out along the region of his back, pulling his tail out first, then moving it to release its head. At birth the fish is about a 16th of an inch to an 8th of an inch long with two black eyes, a long notochord, and a full yolk sac. These transluscent fry should not be disturbed. Do not be alarmed if they fall to the bottom. Within 48 hrs of hatching they will have absorbed their yolk sacs and an air bladder and rudimentary pectoral fin will become noticeable. After about 48 hours they're air bladders will fill and they will start swimming normally seeking food. They will eat anything they can fit into their mouths. This is when it becomes important to have some food on hand
