Rob's suggestion of sunlight to increase hatchability in RFBE eggs has some
merit.
Mine did the best for me in a tank that got 2 -3 hrs of sunlight a day. On
the other hand when I put them outside the dragon fly larvae had a field
day with them. Per haps adding some vitamin D ( which is the one that is
synthesised in the human skin on exposure to sun) to the "pea and prawn"
mix might be worth a try?

Years ago a German aquarist here in Brisbane named Martin Theil used to
add drops of Vit D3 and E to his food for problem fish like Neons and
Cardinals. Although of course they have the problem of the eggs being light
sensitive and once laid the eggs need to be covered until hatched.

I wonder if the eggs (or adults) need exposure to sunlight. Maybe for
vitamin sysnthesis?? I don't know anything about these physiological
aspects. Anybody have any ideas.

I suppose we persist with our breeding populations (until we eventually
develop a strain suitable for captivity) :-(
