My group of Corydoras sterbai spawned, and deposited some of the eggs on the front glass of the aquarium.
Luckily I had cleaned the glass 2 days previous, so the eggs could be filmed fairly easily.

One of the two eggs I had selected for filming hatched during filming on day 6 (day 1 was the day the eggs were laid).

A Canon 600D with a MP-E 65mm was used, the hatching scene at 5X enlargement.

A Zebralight SC51 was used for lighting, it was held inside the aquarium a short distance from the eggs, illuminating them from above and slightly behind.

Hmm…it looks like things are taking a while to load. Try again?
