I have 3 emerald cory catfish. One is a female and the other 2 are males. It is really easy to tell, they are huge and the female is very round. The female is pretty much short and stubby. They are all around 3 inches. I have them in a 29 gallon tank with a couple albino cory catfish. I have noticed that the female has been sort of nudging the males quite often. Is it hard to breed them? I havent really found too much info about breeding them on the web. Oh and below the females anal area it has turned orange, does that have to do with anything breeding wise?

I triggered mine by feeding frozen bloodworms / brineshrimp. They spawned next morning. So far (2 weeks) fry have been as easy to raise as albino cory's, have used same food etc as I do for them with no problems.

What size are yours? Do they have the same breeding pattern as albinos? And should I do a cool water change to trigger them too?

There's at least one breeding report in Shane's World under reproduction for Brochis spp.

Do you have a picture of your "emeralds" as from your comments I think you are referring to Corydoras aeneus when the term "emerald" is usually associated with Brochis splendens, which is no where near as easy to breed as the Cory.

The lady at the lfs said they were green cory catfish. I asked are they also called emeralds, and she said yes. And then I said because they also look like the bronze cory catfish. She also said that they usually dont get bronze cories, she just said that they usually get the albinos, emeralds, and some of kind. But I thought these might be bronze cories. Here are a few pictures of them:

They are , not . So you want to read the article called "So you want to breed cory's" on Shane's World Reproduction section, rather than the one about Brochis...

Ok thats good since they are a lot easier than Brochis splendens. I knew they looked like Corydoras aeneus. I have them with albino Corydoras aeneus, would that affect their breeding? They are 3" now, that is the mature breeding size right?
Thanks for clearing that up

Albino cory's are generally the same species, , which means that they may well cross-breed. Whilst this in itself isn't a problem [you will only get albino "babies" if genes from both parents carry the albino form], I wouldn't (knowingly) sell someone a fish where I don't know if it's carrying an albino gene or not.

It would be better to separate the albino, just in case they do cross, as you'd have "dirty" offspring, as you can't really know who's the father/mother for any particular fish...

3" is definitely big enough to breed...

All the albinos are too small one of the females is about an inch and a half, so I am not sure if they will really cross breed with eachother anytime soon. So pretty much just cool water changes ever couple of days, and feeding frozen bloodworms, and some frozen brine shrimp too. Also I just have one more question: Is it nescessary to seperate the cories while conditioning them? And how often should I feed? And how long would it take them to become conditioned? Sorry for the extra questions

Did you read the article by Ian Fuller in Shane's world?

yes I read it, it answered my questions

Mine are definately Brochis, cool watching the fry developing, the 'hi fin' is starting to show itself on the largest of them and they are starting to show a distinctive '2 spot' kind of pattern (when viewed from above at least).

I split the brood into 2 net breeders, there is a lot of variation in fry size, some being twice the size of their siblings. I moved the largest of them from the net breeders into one of my fry tanks with some albino cory fry this morning, hopefully the smaller fry will hve a chance to catch up without the big fellows beating them to the food.

Well this is kind of weird, but I just checked on my cories, and the bronze corys got a really dark dark color, almost black it seems. Earlier today they were not like this. Does this mean anything?

What's the temperature of the water? I've noticed when the temperature changes, sometimes the color changes. Also, breeding in warmer weather can be a challenge.

the current temperature is 69 degrees
