However, we have noticed an interesting event with those fish: they
congregate around the base of the rock and seem to enjoy the bubbling
falling water. In fact some of the fish are acting like salmon ..trying
to
jump up the waterfall! Most of this activity seems to be happening as the
pond starts going into shade at the end of the day.

My goldies and Koi don't do this much, but the minnows never stop. They must
be exhausted.
