Parental behavior
I may regret this in the near future due to the tone of
the debate that is ongoing, but I would like to point out
that the issue of selecting individuals with egg-eating behavior
by rearing eggs artificially is further complicated by
the fact that, if a selection indeed occurs (I have no
competence in this, and personally I just don't know),
it might refer to the lack of ability to raise eggs in a non-natural
environment. In other words, I am wondering if the strains
that eat eggs might have a behavior more "natural" than
those who don't, given the obvious advantage of re-cycling
energy resources when the ideal spawning conditions
(physical and environmental, such as pH, conductivity,
lack of adequate territory size, etc.) are not present.
So, I am not even sure if egg-eating is a negative or
positive trait: probably it depends on what the acquarist
wants to accomplish, and both views are acceptable.
Take this as an hypothesis from somebody who knows
nothing about ethology.
