Harro. Cary, Rob

Harro's mention of the Red and Yellow strains/forms/varieties of Boesmani
reminds me. Last weekend I visited Eng's fantastic plant pond and he has a
school of Boesies in there flashing around amongst his incredible plants.
The fish all came from John Doley in Darwin and they all were yellow on
arrival but some are a rich deep red and some a bright yellow now.

Promoting the hobby and especially Rainbowfish is the "raison d'etre" for
the IRG and the RSG and a huge part of ANGFA's mission so it is very
important that we fly the flag, show our fish to as many as possible and
insist that the "wild" type is the best model.

However even within those wild populations there are outstanding examples
of "better" individuals or local populations with more colour, bigger fins,
yellow pectorals or whatever characteristic we humans feel is more
desirable. We as hobbyists have tended to concentrate on "fixing" these
models in our sights as the "flagships" for the hobby image for the
species. To some extent we are indulging in the crime of "commercialising"
or perhaps "distorting" the species too.

Perhaps just by breeding them in our differing captive conditions we are
damaging them beyond repair ;-(

This is heavy stuff - I think I might join Rob and play with Livebearers
instead ;-)

Who knows - perhaps I can develop an "alphabet" swordtail that can be
customised to each customer so the can buy fish with their initials
monogrammed on the side ;-)
