  Re: Line breeding vs hybridization

Dear Jim,

Wonderful to have your wisdom.

The choice of Symphysodon in retrospect now seems apt. As a species with
narrow environmental tolerances from in-numerable habitats in a massive
area, it seems critical to keep forms, sub-species, strains, from the
countless wild locations distinct. Given the systems of collection &
exportation, this is at least difficult. Countless different strains of
"brighter" fishes selected from all over the undefined wild are used
"domestically" to interbreed and then inbreed (line-breed) even brighter
"hybrids" with no known pedigrees or common origins. The innumerable "wild"
strains are not domestically pure bred in communities. Genetic integrity is
lost from the moment of collection.

I submit that the genus exemplifies how sub-species & ecological niche
integrity is irretrievably lost on a vast scale before hybridisation.
This is the way I view the distressing unconcern of some animal culture &
horticulture for either the origin or plight of wild species. If the
security of wild species IS assured I care not whether or not they are
hybridised or inbred or both. I do love the best German "hybrid" strains
and both two wild species but I detest the gaudy designer Discus which
retain little of the aristocracy of their more ancient ancestry.

Which species of Spathiphyllum do they still grow in the Aquarium?

Sincerely
