cross bwt 2 species

["Yvan Alleau" <yalleau@coas.oregonstate.edu>]

hi all,
although i am not really favorable to try crossing volontarily some fish
species (or others), i hope at least that the people who would like to try
will do so with species living in the same habitat. Indeed, such a croos
might eventually naturally happen.
I just enjoy the natural beauty and diversity that already naturally exist
on our planet fishwise (and otherwise) as for creating new "species" myself.
I had an accidental cross in my display tank 6 years ago between L.
dorsigera and L. curviceps. Currious if such a cross would work, i've left
the eggs hatch. the fry was growing normally and look great. i nevertheless
catched them and destroyed them. Since then, i've tried not to put in the
same tank species that might cross.
just my 2 euro cents.

PS: interesting subjects and inputs we are getting lately. thank you all

Well said Randy. I have a hard time placing too much stock in genetic
studies myself. For one, as you say we don't yet fully understand DNA, and
second, any lines of distinction drawn between species will be rather weak
because of subjectivity in determining where genetic variation in one
species ends and a new species begins. It is probably unreasonable to expect
any sort of consensus if for no other reason than not everyone is going to
agree about how they will define species.

I do have to agree with Mike with regards to playing it safe, though not
necessarily for the same reasons. The way I see it, if an Apisto can
successfully cross with another form, it's already questionable whether it's
a different Apisto at all. However, even if an Apisto ends up being the same
species as one already described, it may have unique attributes that might
not show up normally, and careless breeding could lose that. That doesn't
mean I have a problem with experimenting. If someone wants to try out a
cross and see what they get, that's fine and dandy with me. Could be
interesting. They should just be honest about it in their dealings and not
try to pass it off as something it's not.

Zack
