Although we can not draw strong conclusions from two tanks of
fish, it sure seems like live food accelerates growth. Not too big a
surprise, I suppose, except for the sheer magnitude of the effect.
Given the basic result you have in hand, it seems more interesting to
me to switch Tank 1 to live food and see to what degree they can
compensate for lost growth. Compensatory mechanisms are known for
many animals (e.g. snails).
