The other nice fish in my pond do get excited when I swing the net around. The pond is a little more than 20ft long and 10ft wide, with multiple levels all lined with boulders (lots of hiding places). Not really sure how deep, but I do know it's deeper than my legs are long. Got very wet the first time I stepped to the bottom level.
I have 12 assorted Goldfish and 14 smaller Koi, all of which are very fond of schooling. I really don't know where I would coral them.
My next morning off I'll try the feeding idea; they are usually sleepy in the morning.
