Corydoras reynoldsi

Hi!

I had several spawn of these Corydoras, but so far all the eggs were infertile...
I doubt that the male is too young as they are full grown...
They have laid their eggs in a mop ( most of the time)
THe water is a tap water with the following parameters: PH7.8, KH8Â°, GH12Â°, conductivity: 300 microsiemens. TÂ° is around 20-22Â°c
I make a water change every 2-3 days of about 30-50% with cooler water that make it drop to ~17Â°c, by the next day the TÂ° is back to the normal range.

Anyone has a bit of idea to turn these eggs into fertile ones...what should I do to have the male fertilize them?

Yann,

Your water is too hard, these fish require very soft water. I use RO water with a little buffer added to raise the ppm to 60, (GH 1 - 2) pH =6.8

Hi!

Well I have used a mixture of R/O and Tap water and 24 hours later around 25-30 eggs were laid, I managed to find 15 of them that are fertile, I placed them in a little nursery and now waiting for them to hatch.
Ian: do you recommand to keep the young in the same type of water after hatching and for grow out?
Cheers
Yann

Yann,

As the fry grow you can very slowly change the water to what you normally use.
