We have a group of corydoras in our aquarium and lately they have started spawning. Typically, there is frenetic activity in the tank with one of the smaller males constantly following and bothering the big female. She’s about 2 inches long, maybe a bit more and fat – so full of eggs you can see them.
When they spawn, the female puts her eggs around the tank, a little bit all over.
I separated the eggs out and into a little aquarium with no other fish.
After a few days the eggs started hatching.
Notice that bulge around them, that is their yolk sacs. That is what they feed off of for the first 1 – 3 days. After that, they need to start being introduced to fish food.

More pics of these baby corydoras coming soon.
