Breeding Cory Catfish

Cory catfish are relatively easy to breed in the home aquarium. They are egg-layers, and will scatter their eggs among plants or other objects in the tank. Once the eggs hatch, the fry are very small and need to be fed microscopic food.

The fry will grow quickly, and can be fed to larger foods after a few weeks. Cory catfish can be bred in pairs or in groups. If breeding in pairs, it is best to remove the fry from the parents tank, as the parents may eat them. If breeding in groups, the fry can be left with the parents, as they will not be as likely to be eaten.

Option 1: Dedicated Breeding Tank

If you are planning on breeding your cory catfish, then you will need to set up a dedicated breeding tank. This tank should be at least 10 gallons in size and should be well-filtered and heated. The water should be clean and well-oxygenated. You will also need to provide hiding places for the adults and plenty of soft, sandy substrate for the eggs and fry.

Cory catfish are egg-layers and will lay their eggs on the substrate. Once the eggs are laid, the adults should be removed from the tank. The eggs will hatch in 5-7 days and the fry will be free-swimming a few days after that. They can be fed newly hatched brine shrimp or commercial fry food.

If you are successful in breeding your cory catfish, you will end up with a lot of fry. You can either sell them or give them away to other aquarium enthusiasts.

Option 2: Dedicated Fry Tank

When setting up a fry tank, it is important to use a fine mesh net to cover the tank. This will keep the fry from swimming out and getting lost. The water in the fry tank should be shallower than the water in the main tank, and it should be well-aerated.

It is also a good idea to add some plants to the fry tank. This will provide hiding places for the fry and help to keep the water clean.

Cory catfish fry are very small and delicate, so they need to be fed small amounts of food several times a day. You can purchase special fry food, or you can crush up flakes or pellets to create a fine powder.

As the fry grow, they will need to be moved to a larger tank. It is best to do this gradually, over the course of a few weeks, to give the fry time to adjust to the new water conditions.
