I was changing the substrate in a small tank today, so I removed the corydoras and shrimp that were in the tank, and discovered, to my complete surprise, 10 baby Corydoras knaacki!
Hardly. October 2015, JRAS auction. I've seen two babies appear before this spawn, but I've never seen eggs. For that matter, I've never seen spawning activity.
They are it again today. I moved them into a different tank last week, and last night they were pretty frisky, after a water change. Found about 20 eggs on the glass and plants today.
