First Clown Eggs

[Oscar]

After 2 1/2 years my clown pair have laid eggs. I first noticed the white mass 5 days ago. They have now turned brown and I think I might be able to see their eyes.

The clowns have been hosting my frogspawn and the eggs are attached to the solid frog spawn stem.

What are the next stages in development I should look for? Anything I can do to encourage survival of the young?
