So, I've been looking at oscar videos since I seem to remember talk about the eggs are different fertilized, and the fry seem a shade of white and the eggs are the same shade white prior to hatching, maybe different for oscars?
The doesn't appear to be many fry, I will maybe wait to concentrate on raising them once the pair are in their new tank and out of qt.
Observation I made is they like to throw gravel on the fry, even on the rock where they laid. Also when moving they kept trying to spit from the pit back to the rock which in turn sent the fry all over the place. Probably just rookie errors
