Bronze Corydora

[debbie888]

Hi

Just asking for information.....have read the topic on breeding corydora's but still feel the need to ask a couple of questions.....Ok just got home and noticed some eggs stuck to the side of my tank....I saw one of my corydora shimmer up the side of the tank and deposit some more, they are white in colour at the moment, I have 2 bronze corydora but do not have a clue if they are both female? Would the female lay eggs if there was not a male in the tank, as I think my other one then came over to the eggs and shimmyed again st the eggs...please help what do I do, my other fish are eating the eggs, I am very excited but also anxious...can anyone advise me what I need to do?

Thanks

Debbie

I have taken a pic of them both, could anyone tell me if they are both female?

Pleaseeeeeeeee someone help me....the eggs are white which I read means not fertilized.......so if I do have 2 females, then I may aswell just remove the eggs?

Oh my lord she is laying them all over, there are loads now and I am sat here with not a clue what to do? I have just counted how many eggs so far and there is nearly a hundred...and she is still laying them....!

The last time my corys dropped eggs, i scraped them off the glass with a blade and put them in a really fine breeding net and added a airstone in it. with the breeding net having constant water passing through it, no waterchanges is needed (like if you put them in tubs) and now mine are growing great and the net keeps very clean for the

I dont know how to sex them but i think the males are longer and thinner where females are shorter and stockier.

If the eggs have been fertilised, they go a dark grey color (mine do anyways) and have a black dot in them, 2-3 days later they hatch.

Like i said im not very clued up on corys but im sure someone will correct me if i have made a mistake

OK many thanks for the reply.....do the eggs change colour then or when she lays them, or when yours did were they grey straight away? All the ones in my tank so far are white...can I expect them to change colour?

Yes they will change from white to a grey colour, think mine changed after about 24 hours ish, i dont pay much attention to be honest cos they rae in the net and i leave them to get on with it rofl


You will soon know though as the colour change is very visible

My Cory barbatus eggs started out a pale brown in colour and within 24 hours the infertile eggs went white.

To sex Corydoras catfish look at them from above. The females will be wider across the body between the pectoral (side) fins. The males will be slender across this area.
The picture is a bit hard to tell but the one on the right is a definite female. The one on the left could be male but don't quote me on that.

You can try scraping the eggs off the glass but quite often that will kill them. If you want to rear up the eggs I would suggest moving the adults into a separate breeding tank and once they have spawned in there, you can move them back to the main tank and rear the young up in safety. A standard 2ft tank is fine for a breeding pr.

Sometimes females will breed with other females if there is no male around. You get heaps of unfertilised eggs. The fish release hormones when breeding and this stimulates other catfish in the area to also breed. A decent sized female can produce several hundred eggs in each spawn.

Ok thanks for the reply Colin...I have tried to get a pic from above, but doesn't look too clear...! This pic is the one on the left in the first pic and I was told by someone on here she thought it was female...so if that is the case and you think the one on the right is female, my eggs might as well be taken out...

The link to catfish11.jpg looks like a female bronze cory.
But even if the eggs are infertile you can leave them there for the other fish to eat. They are really nutritious
