How Often Can You Breed Corydoras?

You lot can breed your corydoras whenever you like as long equally you follow the following instructions for grooming.

1. You obviously demand to pick salubrious fish. This may seem like a no-brainer, simply sometimes the fish are non in the best condition for convenance. If you accept had to medicate your fish for any reason I would suggest waiting a few more than weeks before starting the breeding procedure to ensure salubrious offspring.

If it is near a window you volition need to carry in mind that natural light and outside temperatures volition interfere with the convenance activities in the aquarium.

Instead, have 3 or four females and the same amount of males together in the breeding tank and watch the magic happen.

You lot want to take a larger aquarium prepared, cycled, and ready for activity when your new fry is gear up to be populated should you lot find that your tank isn't large enough for any more companions.

Tank Conditions For Breeding Corydoras

Cory catfish need a tank that holds approximately 30 gallons of water, even though they are only piffling fish.

Call up of the tank'south substrate as your lovely cozy blanket. It's super of import to you, right? That is how the corydoras experience nigh sand. Anything other than sand volition damage the fish and cause them discomfort. That certainly won't get them to brood successfully.

• Plants

Don't overdo information technology on the vegetation in your breeding tank. Having a few well-trimmed plants in the aquarium will make the fry feel safer in their first few days. Java moss, crypts, and pennywoods are good plants to take in your breeding tank.

Identifying If Your Corydora Is Male Or Female

You can not possibly tell the difference between male and female person corydoras when the fish are sexually immature. Well, not unless yous are a cory catfish expert, of course.

Look until the cories are a twelvemonth former, or 2.5 inches long, and observe them in the aquarium. You lot volition discover that some wait a little thicker and chunkier in general. These are females. In comparison, the males are super slim and look like younger fish.

Do Corydoras Change Gender?

Either method works brilliantly, still, less experienced cory catfish breeders should avoid handling the eggs altogether as they are very fragile. Equally long equally the breeding tank is rather minimal and uncluttered, the fry will exist very happy in the tank once the eggs hatch.

Once your fry hatch, they won't demand to be fed for nearly 23-48 hours as they still feed off the remaining yolk sack in their stomachs. One time yous notice the fry offset to wriggle and giggle about more than usual, yous will need to feed them twice per day.

Newborn fry volition merely require powder food in their first week of life. In one case the fry has grown a fiddling (after a week or so of dry nutrient) you can introduce either alive or dead protein. Babe brine shrimp are a effeminateness for cory catfish. On their 3rd or quaternary week of life, you should start to feed them frozen daphnia.

You may observe a fry or two are not quite as strong as the rest, or mayhap they are slightly deformed. If you are convenance your fish for your pleasure then leaving weaker fish with genetic issues is fine. If you want strong fish that will be suitable to brood in the future so this weaker fry should exist separated from the rest.

When your fry is large plenty to motility into the full general population tank, brand sure the tank is big enough to house all of the fish. If y'all practise not have a large plenty tank and do not wish to have a bigger tank, give some fish abroad.
