We just stocked 35 RBT in our little backyard pond 6 weeks ago. Our water is so much smaller than yours our experience is hardly comparible. Still, I can tell you that you quickly find yourself watching the clock each evening waiting for feeding time. Given our scale we hand feed but to be honest knowing what I do know I think I would elect to hand feed regardless as the show is just plan fun.

Feeding time is growing into a neighborhood event with my local farmer friends stopping by just before 6:30 to join me pond side. What a blast !
