Carl:
I just learned from a DVD that Dragon Fly larvae eat koi fry...The fry that survive and grow larger then eat the larvae in payback...
Not sure about the water walkers... I know some guys (outside the koi community) who think they can walk on water, but generally they're just pains in the okole...
Talk about payback: Tonight's menu...Hot steamed rice, 1" thick rare grilled Teriyaki Steak and sweet corn... Broke the mout!
Aloha! Mike
