So, we have decided to write this article for you.

Baby Black Moor Goldfish

How do black moor goldfish reproduce?

Moor goldfish, like most other varieties of goldfish, reproduce by spawning.

This simply means the female releases her eggs, and the male fertilizes them. The fry (baby fish) will look very different from their parents. They will be a pale yellow color and have long, thin tails.

How long will it take for the fry to grow?

It will take around four months for the fry to grow to a mini version of adult goldfish.

Until then, all goldfish varieties will have the same characteristics: a small body, large head, and long fins.

Black moor fries start to form their adult shape after five weeks of age and become juvenile fish after about 3 to 4 months. They will take another 2 to 3 years to reach full size.

How quickly do black moor goldfish grow?

The growth rate of a black moor goldfish depends on the tank conditions and how well you care for them.

Usually, fish fries that live in perfect tank conditions and have a high-quality diet will grow about 1/2 inch per month. If conditions are not perfect, the growth rate will be slower. We call this the stunted growth rate.

What do black moor goldfish eggs look like?

Black moor goldfish eggs are very small and hard to see. They are usually a pale yellow color.

These eggs get stuck on the substrate, decorations, and leaves of plants. They will look like tiny bubbles and are incredibly sticky.

If you want to remove these eggs to another container, you may have to pick up the media (leave or decoration) and replace it as these eggs are hard to remove.

What do baby black moor goldfish eat?

You can feed your fry a variety of things. They will eat commercial fry food, brine shrimp, daphnia, and bloodworms. 

You can also give them shredded lettuce, peas, and zucchini. It is essential to provide them with a varied diet so they can grow healthy and strong.

Once they reach the juvenile stage, you can feed them adult goldfish food. You can feed them pellets, flakes, or even live food. Algae wafers, vegetables, and fruits are also good choices.

How to take care of baby black moor goldfish?

You will need to set up a separate tank for your fry. This is because they are very small and need their own space. Otherwise, adult fish may eat them. 

The tank should be at least 10 gallons and have a lid. You will also need to have a filter and heater.

You can start by feeding the fry three times a day. As they grow, you can reduce the number of feedings. Once they reach the juvenile stage, you can feed them twice a day.

You will need to do a 25% water change every week. While changing water, you can use a gravel vacuum to clean the bottom of the tank.

As your fry grows, you will need to upgrade to a larger tank. A 50-gallon tank is a good size for juvenile goldfish. But, soon, you will have to buy more tanks or sell away your black moor babies because they need more and more space as they grow up.


Baby black moor goldfish are beautiful fish you can keep in your aquarium. They are easy to care for as long as you provide them with the right tank conditions and diet.

With a bit of patience and following tips and info in this article, you will be able to watch them grow into healthy and strong adult fish.
