Breeding Corys!

[3006Kelly]

Hi, can u tell me whether it is possible to breed corys in a community tank? I was just wondering cos i have my bronze cory having loadsa eggs (which obviously get eaten by greedy mollies and guppies) and wondered if i could place the eggs in a breeding net? Also if this is possible, wat special treatment would i need to give them . Thanks in advance, kelly
p.s. hoping to get a cory species tank up and running soon but cant afford it yet!!

It is difficult to keep eggs from being eaten in a species only tank as well, with some kinds of cories. In a community tank it is possible to breed cories though. You need to be vigilant and as soon as you see eggs in the tank you have to remove them. A net breeder would work just fine for the purposes of keeping the eggs and fry away from the other fish in the community aquarium. I have found that the fry who are kept in a net breeder have a higher mortality rate than those kept in their own 10 gallon grow-out tank. A breeding tank for cories is not that expensive to set up. All you need is a bare-bottomed ten gallon (US) aquarium (which cost less than 10$ here) and a air driven sponge filter. I use a sponge filter because I can keep it in a mature tank when the breeding tank is not in use to keep the nitrifying bacteria populating it. The cories you want to breed you should place in the breeding tank and condition them by feeding them frozen bloodworm, blackworms, Grindal worms, etc. When you see the female(s) plump change a portion of the water with slightly colder (1 or 2 degrees) right before you turn the lights out for the night and you might get lots of eggs on the glass the next morning. Once you get eggs remove the adults immediately to keep any eggs from being eaten, and place an airstone under the eggs to keep the eggs from fungusing. When the eggs hatch, after 3 to 5 days, you will not need to feed the fry for a couple of days because they still have a yolk sac in their bellies.

Here is a picture of a newly hatched Panda Corydoras with a visible yolk sac (the large black bubble in his belly)

Once the yolk is used up begin feeding the fry baby brine shrimp and/or microworms.

Again it is possible to breed cories in a community set-up but your yeilds will be much higher in the process I described above.
