A Beginner’s Guide to Goldfish Reproduction
While goldfish might be small, they are a colorful fish that actually have comical personalities. Many people purchase this particular fish to keep as pets but others are more interested in goldfish reproduction for food, which would be used to feed larger fish and snakes. Regardless if you want to breed goldfish to sell as pets or for feeding purposes, you will learn everything you need to know to be successful.
The process of goldfish reproduction is also referred to as spawning and in truth, it is easy since this fish spawns on its own. Whether you keep fish in an aquarium inside the home or larger goldfish outdoors in a pond, the breeding process is something they take care of. However, for fish to breed and multiply, the key is providing them with the proper environment.
When goldfish get ready to spawn, they go through a courtship, splashing around in the water and when done, eggs are laid. These eggs are somewhat sticky so they automatically stick to the surface of the aquarium or pond. For this to happen, goldfish need to have clean, clear water, which is the result of frequent water changes.
For goldfish reproduction to work, the tank or pond should be void of any gravel or sand. One of the best methods to be successful in breeding goldfish is to purchase an inexpensive breeding tank. Inside the tank, all you would need is live plants, placed around the bottom of the tank or pond. While eggs will stick to the sides, fish also love laying eggs inside these plants.
The temperature of the water inside the aquarium, pond, or breeding tank needs to be maintained two to three degrees F lower than the normal water temperature. This means keeping the water around 60 to 61 degrees F. A good thermometer designed for a fish tank is all you need. If the water becomes too warm, simply add cool water and if it becomes too cool, add warm water. Just be sure the additional water is added slowly to avoid shocking the goldfish.
Next, the goldfish reproduction process would involve placing one or two mature males in with a single female. If you are uncertain whether your fish are male or female, again, someone at the pet store could assist or you could simply place about ten fish in the tank assuming that you have at least one male and one female. From there, you simply sit back and let nature takes its course.
It is also important to provide the fish with extra food and even live food during the spawning period. As a part of the goldfish reproduction, the male will begin chasing the female around, soon followed by tiny round-shaped eggs. As soon as you see eggs being laid, it is vital that you remove all of the adult fish so they do not eat the eggs just laid. Remember, one female goldfish can lay literally thousands of eggs at a single time.
With the eggs laid and the adults out of the tank, the water needs to be warmed between 64 and 69 degrees and then in approximately four days, the eggs will hatch. At that time, baby goldfish, known as fry, will begin to cling onto the side of the aquarium or pond. The new fry will need brine shrimp for food, allowing them to reach maturity in four to five months, completing the process of goldfish reproduction.
