I had my iPhone handy but it doesn't zoom during videos so I had to take this video some distance away so I wouldn't disrupt their mating.
You'll see Stevie Fishnick (the platinum angel) move her belly up the leaf, laying eggs.
Then Lindsay Buckingfish (the black marble) will follow along the path of eggs, fertilizing them.
They will continue with one row after another until they have around 300 eggs on the leaf.
Tomorrow: pictures from the first batch of baby angels in their new home!
