Severum Spawned!

[Skippy]

I discovered a pair of my green severum's spawned the other day. Suddently I have a rock coated with these golden colored eggs. All are tranluscent, except a few which have gone opaque. I assume like paradise fish those are the infertile ones? Am I right?

They seem to pick off and eat these opaque eggs.

About how long until eggs hatch for Severum? This is my first experience with them spawning? Any old pros with Severums out there?

UPDATE -

Unfortunately the parents after about 3 days of tending to the eggs seem to have eaten them. Does this mean they were infertile? I swear I saw at least one wriggling.

Can you remove the rock they spawn on and hatch the eggs in a fry tank?
