I have some problems in breeding Corydoras virginiae.
I'd like to get a piece of advice from those who has succeeded in doing that.
Half a year ago I bought 11 C. virginiae of about 3.0-3.5 cm. SL.
Now they are about 5.0-6.0 cm. SL.
They like to eat much.
They live in an aquarium 70x35x35 cm.
In the last month I change about 30% of water either daily or in a day. The water is 3-4°C lower than that in the aquarium.
T° = 23 - 25°C in the day and 19 - 22°C at night.
pH = 5.5 - 6.0
Conductivity = 80 - 120 mS.
I have never seen breeding activity up to now.
