Anyone out there familiar with breeding bettas (aka Siamese fighting
fish)?  I've bred blue and multicolor strains for a while, but decided
to try reds a few months ago.  I spawned a red female from an excellent
strain with a nice pet-store red male.  The young are between 0.5 and
1.0 inches long now, and with the exception of their heads and backs
their bodies are light-colored (rather like Cambodian bettas).  Does
the extended red characteristic usually appear late?  The entire spawn
has this coloring, and though I'm not that familiar with betta
genetics I would expect at least SOME of the fry to have different
phenotypes if hidden/recessive genes were at work.

I also have a pair of blue single-tails that have produced double-tail
offspring.  The problem with these double tails is that instead of
a completely split caudal fin they have something more like an
indentation.  So now I know that the double-tail gene is not Mendelian
(in oher words, it can appear in various degrees).  My question
is, how much can it vary?  If I reduce the double-tail characteristics
a bit more, I feel I could end up with a very nice single-tail strain.
Is this idea worth pursuing?
