Pregnancy is not a thing in an egg-laying fish so you might have to look at the gravid body of the fish to know if your female Cory catfish is carrying eggs or not.
Your female will be carrying eggs in their tummy from the moment they hit maturity. When male Cory catfish woos the female to lay eggs, then the gravid body of the female decreases and becomes slightly normal. And if you are thinking about the hatching period of the eggs, then that is nearly 3 to 6 days after the female lays eggs and male Cory catfish fertilizes them. The gravid body of the female is the evidence that your Cory catfish is carrying eggs.
The development of eggs starts from the very beginning of maturity. Cory catfish male and female show the spawning behavior for nearly an hour or more. And female Cory catfish will lay eggs in various places. The number of eggs varies from 50 to depending on the number of eggs female Cory catfish is carrying.
Each time they form the t shape and the female cups her ventral fins, she will lay nearly 4 to 12 eggs in her fins. After laying eggs in her fins, she will place them in the glass or leaves of the plants in the fish tank. Female Cory catfish will take a rest for a while before starting the same process again. So, when the spawning session finally ends, you will see nearly 50 to eggs scattered all over the tank in different locations.
When the Cory catfish start showing the spawning behavior in the tank, you will see the eggs in the fish tank wall in no time. Female Cory catfish tend to lay eggs on the leaves, plants, decorations, or the walls of the fish tank.
You will have to look for small whitish jelly-like balls in the tank which will probably be with other eggs together. The clutch of eggs will be attached to the walls and decorations and will be easily identifiable.
The eggs will be nearly 1. Finding out how many fish fry you are going to get can be really exciting. But this will only be possible if you know how to differentiate between fertilized and unfertilized eggs. You might already know that only the fertilized eggs will hatch to become fry and other ones will stay in the tank with no further development.
The unfertilized eggs will rot after a while and you will have to remove them immediately after to find which ones are unfertilized. Now let me tell you the difference between two eggs. The fertilized Cory Catfish eggs will look slightly beige in color.
You can increase the oxygen by using a sponge filter, an air stone, or an air pump. That will prevent your water from getting stagnant. All I do is placing that device in the middle of the tank, and it takes care of the rest. Performing a water change is an essential part of maintaining the quality of your tank water. In the case of breeding a species of Cory Catfish, you may need to perform more frequent water changes to keep your tank free from ammonia.
You may also need to use some additives like ammonia remover and pH down for this purpose. It usually takes three to five days for Cory Catfish eggs to hatch. It may take longer than that if the water temperature is lower than 82 degrees Fahrenheit. In higher temperatures, the eggs hatch sooner. You can tell that they have hatched when the outer membrane has been absorbed inside the egg. If you touch the egg and it feels sticky, then it has not hatched yet.
When it is ready to hatch, the egg will feel smooth, and you can see the babies moving inside. When the eggs begin to hatch, you may see two or even three babies swimming nearby. Cory Catfish do lay unfertilized eggs. This is a common occurrence when the female Cory Catfish is introduced to a community tank. The female lays these eggs for several reasons: as an act of aggression towards another fish , if she has not mated yet, or if she was stressed out and her body is producing more than one clutch of eggs at a time.
You can tell if a Cory Catfish egg is fertile by observing it over the next few days. An infertile egg will usually deteriorate and lose its teardrop shape, while a fertile egg will become more oval-shaped over time. A black dot on the surface of an egg is usually a sign that it is fertile. The fertilized eggs will hatch after three to five days, and the babies will immediately begin feeding on tiny plankton.
Once they start eating, you may notice small strands of threadlike filaments coming from the mouth of the babies with each bite. Do not get tempted to decorate the new tank because you will sabotage the whole process. How can you condition your Catfish to spawn?
Easily — make them happy. Make sure they are stress-free, that they eat good food high in protein, and try adding live food as well. This will simulate a summer rainfall, which is the season in the wild when Cories breed.
It might take up to a few days, and when females lay eggs, they will do it on the walls of the tank and plants. If you went for the second strategy and allowed your Cories to breed in the main tank, now you will have to get the eggs as fast as possible to the new tank. You can do that by using your finger or an old credit card and gently scraping it off the walls.
If the eggs are on plants or ornaments, you can take them whole and move them to the new tank. Also, if you notice any infertile eggs, remove them as they are probably developing fungus and will contaminate the rest.
The eggs hatch in 3 to 6 days. For the first few days, they will feed off their egg sack attached to their bodies. Once they start swimming, you should start feeding them the food designed for the fry specifically, such as New Life Spectrum Fry Food.
Once they grow up more, you can switch them to adult fish food. To sum up the settings for a breeding tank and place where the fry will live :. Once the fry has hatched and you have moved the parents back to the main tank, it is time to think about what to feed them and how to raise them in general. They will be very small, so you will have to feed them really small amounts of food. You can feed them small amounts of newly hatched brine shrimp several times per day. If you do not know how to hatch brine shrimp, it is very easy, and you start the process two days after the Cory eggs are incubated.
After a week, you can start feeding the fry with crushed flake food or even with live brine shrimp, if you have them.
You can also feed them with daphnia and micro worms. It is also very important to keep the water clean and never overfeed the fry. Replace it with the water from the main tank. By the time the fry is 3 to 4 weeks old, they are large enough to feed on regular tank food and you also can add a regular hang-on or canister filter without injuring them.
Few more weeks and they are large enough to mingle with other fish.
