first of all, perhaps I'm going to try and keep a couple of these fish in
a 50l tank (I'm doing things metric, just to be clear ), if you think
that's a bad idea, please say so.

but there's a thing I wonder about: inbreeding. I've got a book by Pierre
Brichard about the cichlids in Lake Tanganyika (german edition, "Das
grosse Buch der Tanganyikacichliden, 1992), and it outlined the history of
the species in aquaria. it seems that at that time ('92), the species
suffered from inbreeding because they were all descendants of very few
specimens caught in the fifties and that at that time, importing had just
started again.

the thing I wonder about is this: how is the situation now, are there now
better specimens available? I don't necessarily need wild caught fish, but
I'd hate to have fish that are degenerated due to human intervention, as
the book was written in '92, I wondered whether the situation has changed,
for fish in general and J. ornatus in particular.
