OK, all you fishkeepers with a passing interest in physics (or physicists
who keep fish), this ones for you -

Given an aquarium holding X amount of water at 75 degrees F, what is the
maximum amount of water (in terms of X) at 55 degrees F that you could add
and lower the temperature of the total less than 3 degrees F?

For the purposes of the exercise, the air temperature surrounding the
aquarium is also 75 degrees F, and discount any possible radiation or
absorption from rocks, the glass, decorations, etc.
