RE: raising cichlids without their parents



If the colors and other physical characteristics of fish can be selected in
just a few generations, why can't behavior as well be selected in a short
span of time?

Natural selection of a species of moth in England took less than 10 years.

And yes, natural selection compelled these instinctive behaviors into the
fish, but it took millenia, not three or four generations, to achieve.  My
contention is that it would take dozens, nay, hundreds, of generations for
genetically poor parents to  gain the upper hand over good parents in
captive
breeding.  And some of us are still giving the good parents the advantage,
and
therefore the instinct will survive.
