sexing Laetacaras

[Piabinha@aol.com]

how does one sex these cute little monsters?  

i thought i had a female curviceps so i went out and got her a slender fish,
with more pointy fins, which i think it's a male.  now she is getting pointy
fins too, although she is still very heavy.  am i correct in assuming that
females do get very pointy and elongated fins, and unlike apistos, that is not
a sexual characteristic?  same thing with my thayeri pair, both seem to be
developing long fins, although i had picked one with less prominent finnage
than the other.

i also have a M. altispinosa pair where the smaller fish didn't have those
elongated fins (caudal and dorsal) but then it started developing those and i
thought, uh oh, i have 2 males.  but it also shows an ovipositor, so i know
it's a pair.  of course, they have not shown any interest in starting a family
yet...
