Re: eggs
The largest disparity in color that I have seen is the difference in the
color of Lamprichthys tanganicanus eggs that Joe Bulterman collected and
those I collected from the same strain of the species. His were always orange
and mine were nearly colorless. Both hatched OK, so the viability was not
questioned. We agreed that something about our feeding regime or our water
was causing the difference.
On the issue of visibility, I have observed that very few eggs of any
species adhere peat particles when freshly laid. Some do gather particles
later and become nearly impossible to pick out of peat. Others, like
Maratecoara lacortei, stay non-adhesive, seemingly forever. Aphyolebias
peruensis eggs are difficult to see even when fairly newly laid because they
are not as clear as others. However, the spherical shape is clearly visible
with transmitted light, but not with reflected light.
