Corydoras paleatus - Breeding Size

Good Afternoon,

Being a relative newcommer to breeding Corydoras I would regard myself as being quite sucessful as i have so far managed to breed 5 types in past 9 months or so (, , , Corydoras aeneus Albino & ).

By far the easiest and most prolific have been the . I have a small group of 7 or 8 individuals which seem to be laying eggs a couple of times a week minimum, with the occassional week gap depending on how hot the weather is. The breeding group is housed in a 4 ft community tank and most of the fish seem to leave the eggs alone long enough for me to collect and place into breeding nets which i have in good flow parts of the tank. Once they are a 4 or 5 weeks old and feeding ok i transfer them into a 2ft grow out tank which seems to work well until they are large enough to sell on to my LFS. On saturday I noticed that the last batch of fish approx 6-8 weeks old (i should really keep better records) have started laying eggs already.

Ive never had this before with such young fish. Should i try and seperate males and females as soon as i think i can tell them apart or just leave them to get on with it? Ideally i guess its not a great idea to leave them as they could be related?

I am also currently trying to condition 2 other groups of Corys ( & ) so will update as and when there is some progress.

Any thoughts greatfully received.

Regards,

Darren

Greetings Darren. I would venture to guess that your 6 to 8 week old fish are not laying eggs. While I used to believe that it took a year for most Corys to reach sexual maturity, I have found 9 months to be a more realistic figure. I have never witnessed any group of Corys spawn in under 7 months and I don't think you will find many, if any, Cory keepers who claim to have documented any spawns in less than that time frame.

Just my 2ยข. I'd be curious to see what others have to say on the subject. Cheers. - Frank

The small species (hastatus etc.) will spawn from around 6 months. Other than that 9 - 12 months seems to be typical with a few species keeping you waiting much longer.
