John,

I never doubted for a second that this would be a problem demanding a
database-solution. One particular aspect that I'm having trouble with is
this:

given a selection of fish so far, which all fall within say temperature
range R1-R2;
given the desire to select a new fish, whose inclusion might change either
R1 or R2 or perhaps both, in such a way that Fish1 and Fish6 may no longer
be able to handle the new temperature range (too cold now or too hot), then
drop the new one or the other two?
