I want to breed cory catfish. Can you help me?

Question

1. What size of tank do I need?
2. What temperature do I need?
3. How many cories should I start out with?
4. What should I do to stimulate breeding?
5. How much should I feed the babies and what should I feed them? What should I feed the adults?
6. At what age/size can they mate?
7. Anything else I should know?

Please answer all the questions and number them.

Thank you so much!

And do the parents eat their babies?

Answer 1

1The minimum tank size would be 30 gallons.

2The temperature should be around 78F

3You should start out with a group of 6-7 young cories

4To stimulate breeding, do a large waterchange (50%) every day with water that is 5-10 degrees cooler than the tank water.

5Babies will forage, like their parents, for detritous. You can add liquid fry food or powdered egg, bbs, artemia, daphnia, too. Adults will eat sinking pellets, bits of fishfood, etc. Feed quality foods, and lots of variety, to keep the adults conditioned for breeding.

6Size and age depends on the species. Larger cories can reach 3-4" and will breed at 2.5", or 7-8 months. Smaller cories will breed at 1-2", at 6-7 months. It can, of course, vary.

7You should have a tank with JUST corydoras if you want to breed them. Otherfish will likely eat the fry before you even know the parents spawned, because as soon as the hatch, the first thing the fry do is swim to the surface to take a gulp of air to fill their swim bladder. So, also ensure that the water is not deeper than 30cm. Decoration does not really matter, but a couple caves (like coconut shells) should be provided. Plants are optional, substrate should be sand...
If you notice the eggs get fungussy, put in 3mL per 5 gallons of hydrogen peroxide every day until the eggs catch. You can also increase hatch rates by carefully collection the eggs and putting them in a breeding net.
Yes, the parents will eat the fry.

Answer 2

1.) the tank size depends on how many cories you are going to have in there. I would have to say 8 in sq for each pair. That means an 8 in square at the bottom of the tank.
2.) Around 74 should be good.
3.) Depends, have you been around fish for a while? If yes then as many as you can make space for. Otherwise start out with just a few. Sexing them will be difficult because they are almost identical
4.) provide alot of rock and plant cover. Rocks into caves, carpet plants and use smaller rock or even sand
5.) If you decide to leave them in the same tank then you should feed them brime shrimp, live or dead. Or you could seperate them and get baby brime or dead and feed the babies that.
6.) Once they are full grown they can boogie down. Which means a little over an inch long
7.) If you leave the adults in with the babies some of the babies may starve. Unless you feed them multiple a couple times a day or larger amounts
8.) The babies most probably won't get eaten but they could starve I would suggest sepperation.

Answer 3

30-50 gallons, with lots of floor space. Anything taller than 18 inches is a waste for breeding cories. You can decorate with sand, and lots of large leaved plants. Java fern and anubias are good. Floating plants may also be a wise investment, but NO SNAILS. Cories lay eggs on smooth surfaces. They seem to prefer the glass sides of the aquarium over anything else. Plant leaves, slate, and pots are a close second, but if you want anything portable for them to lay eggs on, your best bet is to decorate with anything smooth and clear. My greatest success came from decorating with piles of breeding trays.

A sandy bottom is recommended, and cories like to stir this up, so filter intakes should be set well above the bottom of the tank.
Water conditions should be soft and acidic. A slightly lower temperature of 60-71F or so may be best for breeding

They love live food, so if you can, go ahead and fill the tank with tubifex, daphnia, and rotifers before adding any fish. If you decorate with breeding trays, these creatures will have natural "reserves" from which to continue breeding. Their natural habitat is also rich in algae, so there's no real reason to clean it off.

It'll take them about a week to settle down in their aquarium, and regular (nearly constant) small water changes may be best for breeding. They get pretty frantic when they breed, but eventually, the female cleans off a spot, and sticks a bunch of eggs to it. They look like little clear-white pin heads.

You should have twice as many males than females, with as many fish as possible in the tank. A second tank, either a small one for eggs, or a larger one for the adults is recommended, as they like to eat their own eggs. The females become fatter than the males at breeding time, but you can sometimes tell them apart by the dorsal fin (on top) which is more pointed on males.

As the fish often eat their own eggs, you should move the eggs (keeping them under water) to another tank, or move the fish out. Fungus can be a problem, so use antifungal stuff. About 4-6 days after laying the eggs, about a third of them will hatch. These young live off their yolk for 2-3 days, after which they must be fed infusoria, and the smallest possible foods you can get. In 2 weeks, you can get up to daphnia, and freshly hatched brine shrimp. They grow fastest in regular water temperatures, of 68-82.

Answer 4

both above me are correct, however you should be able to pull it off with 5 cories in a 20 long or more in a 40 breeder. try just yahooing or googleing cory breeding, I found a good site on this before but have lost it as I went on to do the live bearers and convicts.

and i think java moss may help the fry hide from the parents as they may eat the fry, most fish do.
