They look good to me. What strain are the parents ?
You may get a difference of opinions from others but if you know which pair formed you can pull them out in a separate tank along with eggs but the chance of them tending to eggs are not likely.
There is another option is to get a floating breeder box inside display tank and place magnet with eggs inside along with a small air stone set really low just enough for current as the parents would do when they fan them.
Something like this.... http://forum.simplydiscus.com/showth...Rearing-of-Fry
I would try the second option and if they hatch I would consider getting the parents in their own tank...
