No one, that I know of. When I said "captive diabolis offspring" I was referring
to refugia population. Sorry for the confusion.

>When were they reproduced and raised to the point of developing pelvic fins?

I don't know. I read this in an AKA publication, which cited a paper by Baugh
and Deacon on refugia effects on Devils Hole pupfish from Zoo Biology. I haven't
seen this paper; it's on my "to copy" list the next time I make it to the Univ
of MD library. Do you have it?

BTW, the AKA ref. said "rudimentary pelvic fins," if that makes any difference.

I would be very interested in reading this. Is a publication pending?

I didn't know that! Thanks for sharing. All the more reason to be extremely
careful with captive (refugia) stock. And all the more reason why an aquarium
population -- assuming it reproduced in captivity -- might cease to be true
diabolis over time.
