Bill, possibly of interest to you:

http://www.gunpowderaquatics.n.....o-longfin/

my understanding is that danio hybrids tend to look like zebras (yes, it does) and tend to be sterile or almost

(ps. it is so difficult to use this forum lately that i need to apologize for not replying to previous posts or perhaps not replying to this thread too)

I have not read this particular one but saw this summarized elsewhere ... cannot remember where now... possibly P.Cottle's site.

I'm actually curious about the hybrid's strain virility.... just not enough to get it.

Its my recollection that Danio fertile hybrids (generally speaking) are not very common or robust.

If you get some that can breed and breed, them they don't improve much.

It might be possible to backcross to one of the original species to get a more normal set of chromosomes and a more robust hybrid.

My recollection too, and Cottle (danios.info) says this also.

No, I really do not see a point of having these things around, only curious if they managed to get them indeed fertile/robust enough to farm-breed.

Researchers would like them because they would provide a lot of genetic differences that could be used for molecular genetic mapping of mutants (mostly from zebrafish). This has not worked out, because of their reproductive problems.

Certainly no true of all fish. Platies and swordtails are a good examples of fish that hybridize well and have produced nice fish, but that group has a recent evolutionary history of hybridization.
