How to Stop Cory Catfish From Breeding: Tips and Facts You Should Know

If you’re looking to keep cory catfish in your aquarium, you’ll need to know how to breed them. Corys are a type of catfish, and as a result, they are easy to produce. So you need a tank large enough for the number of cats you want to keep, some live food such as small fish or bugs, and some water conditioner. But, on the contrary, how do you stop them from breeding?

There are a few ways to stop cory catfish from breeding. One way is to remove all rooted plants and decorations from around the tank, as these may provide shelter for the corys. Another method is to use an aquarium cleaner explicitly designed for cleaning fish tanks, which will eliminate any unwanted bacteria or debris that could encourage spawning. In addition, you should also vacuum your tank over a week or so before bedding any new fish. This will remove any slight remaining bits of the substrate, which could breed between layers.

Why Do Cory Catfish Breed Fast?

Cory catfish are commonly known for their breeding habits. They have short spawn cycles of just 5-7 days, and with no netting or bottom cutting, corys can breed up to once in a week or two! This is why it’s advisable to remove uneaten food from the tank at least once a week when you first get your fish so that your other fish don’t poop them out before they can breed.

What Makes Cory Catfish So Special?

Corydoras are some of the most popular catfishes globally, mainly for their beautiful coloration and calm temperament. They are also relatively easy to care for and can be kept in a small aquarium with other peaceful fish. In addition, they are not as territorial or aggressive towards each other as some of their other close relatives.

When Are Corydoras Old Enough to Mate?

Corydoras reach sexual maturity around two years old and will begin to breed when they grow to about four inches long. In the wild, corys usually deposit their eggs in communal nests, so you mustn’t introduce any new fish into your tank until all of the corys have left. Therefore, when choosing a new home for your fish, be sure to choose an aquarium that is large enough for them all and has plenty of hiding places.

How Often Can You Breed Corydoras?

Breeding corydoras is like harvests; it’s essential to plan your breeding sessions to achieve the best results carefully. The number of times you can breed them will depend on their age, size, and temperament. Generally speaking, they can breed every two weeks if adequately conditioned and have plenty of swimming room.
