HOW TO BREED CORYDORAS CATFISH IN AQUARIUM

BREEDING CORY CATFISH

If you have a tank full of corydoras, count yourself very lucky! You will be able to introduce other similar temperamental fish to the aquarium without getting any trouble from your cory catfish. In fact, if you have tetras or other similar colored fish in the tank, the cory catfish will swim with them playfully.

Another benefit of having a school of cory catfish in your aquarium is that they will help keep your tank clean. Corydoras are bottom feeders. This means that they spend most of their lives at the bottom of the tank, looking for leftover food and other debris to nibble on. Bottom feeders, in general, are great tank companions for messy fish and make your life that much easier when it comes to cleaning the tank.

Corydoras Fun Facts
Female corydoras are a little larger than males. They can grow up to 3 inches long, while the males reach roughly 2.5 inches.
Adult cory catfish don’t have teeth. You may notice small teeth-like ridges on larvae and young cory catfish. They soon lose those baby teeth and are left as gummy adults.
Cory catfish live for a maximum of 5 years. They will only reach this age if you keep them happy and healthy. Do not forget that the happiness of your fish is just as important as their health.
Corydoras can’t get pregnant. They are egg-laying fish, so they do not give birth to live larvae.
Corydoras aren’t fussy when it comes to their food, they will eat both plants and meat.

Did you know cory catfish can breathe out of water? They have a special labyrinth organ which is vital for land breathing. Do not keep your corydoras out of the water for very long though, as this will get them very distressed.
They love to eat, but make sure their meal sinks to the bottom of the tank. Cory catfish are a little lazy and would rather their meal comes to them.
There are about 7 types of corydoras, each of them have their own distinct pattern and coloring.

Corydoras like to eat zucchini and squash every now and then.
Corydoras can breathe atmospheric oxygen through a labyrinth organ and will often surface to take a breath of air.

Corydoras And Egg Laying
Corydoras, like many other spawning fish, have a tendency to eat their own eggs. Therefore, it is important to separate the cory catfish from the eggs as soon as the eggs have been laid and the spawning session is over. The most important part of looking after the eggs is actually ensuring the adult fish are out of the tank ASAP to prevent the corydoras from eating their fry.

Corydoras eat their own fish in the wild too. This is their way of controlling their population. We are unsure if corydoras eat eggs that they think are genetically impaired or if they just do it as a survival instinct.

The fry tank and the breeding tank can be the same. Although corydoras can spawn in their regular community tank, it is best to move them so that you don’t have to handle the eggs.

Make sure that the breeding/fry tank is fully cycled before prompting your fish to breed. This tank should be as simple as possible, no need for fancy accessories in your breeding tank as that just makes it that much harder to clean.

Corydoras eggs take just 3-5 days to hatch, hence the importance of having a breeding tank ready and cycled. If you are having trouble cycling your tank, use a good water conditioner and beneficial bacteria to speed up the process a little.

Cory catfish females will swim with their fertilized eggs to a flat surface for depositing. They like to place the eggs on something soft like moss.

You obviously need to pick healthy fish. This may seem like a no-brainer, but sometimes the fish are not in the best condition for breeding. If you have had to medicate your fish for any reason I would suggest waiting a few more weeks before starting the breeding process to ensure healthy offspring.

Next, you need to reassess where your breeding/fry tank is to be situated. If it is near a window you will need to bear in mind that natural light and outside temperatures will interfere with the breeding activities in the aquarium. Try and move the breeding tank to a quiet, dark area of the room so that you have control over the light. (13 hours of soft light per day is perfect)

Place a little hiding spot in the tank. This can be something super simple like a large plant or a cave of some sort (broken coconut shells are great for corydoras).

Do not try and breed one corydoras couple at a time. As we mentioned earlier, they are extremely social and will not ‘get in the mood’ if there are just a couple of fish in the tank. Instead, have 3 or 4 females and the same amount of males together in the breeding tank and watch the magic happen
