Re: Aplocheilichthys normani, Fundulopanchax Scheeli hybridization?

["Dave Wood" <daviduu at btinternet_com>]

Tony T shot me down in flames re-hybrids (to a degree). My point was that
(as a general rule) unrelated species won't interbreed. Sure, we can produce
hybrids. I've done it myself (accidentally) with killies and cichlids** and
agree that some hybrids are not clearly different from the parent strains.
Some hybrids are beautiful, and some are not.
Some are viable (such as the red-parrot cichlid.)
Although gardneri and australe cross, and so do strains of BIV, one would
hardly expect (say) sjoestedti and Epiplatys dageti to cross.
I suppose that we must remember that genera are not cast in stone, but are
man-made labels.
(** I crossed H. cyanoguttatum with T. synspilum.)
