Seconded. My ex-in-laws used to have a koi pond that they had to keep netting over, because a heron had decided that this was *his* pond. They lost 5-8 rather large koi (like, 8 inches and up) before they put up the netting. The heron kept coming back for at least 3 years. He'd sit on the top of the roof overlooking the pond and stalk. You couldn't actually scare him away.
Heron, yes, not egret. But yeah, they're a big problem with koi ponds. There are a range of products sold at places that sell acquatic plants and pond systems to deter them. My favorite was the motion detector attached to a hose for squirting anything moving at the right height (turn it off if you're having guests over).
They will eat your entire pond. Near me is Lilyponds, MD, which is pretty much a giant koi farm, and there are always herons around, looking for food. The owner of the place says that several times they've had breaches where the herons got in and ate so many koi they couldn't fly afterwards and had to be chased off the property on foot.
Nah, they carry them around in buckets. I have a bit of a hard time taking it all that seriously, but my brother (the marine biologist who manages a huge aquarium shop) says that fish breeding has a few advantages over dog breeding- a good koi can live many decades, produce dozens to hundreds of offspring per breeding, and you can pick the best out of those many thousands as the ones you want to keep, with much less ethical debate than you would with dogs or cats or horses.
But I doubt they have an agility course and very few of the contestants passed obedience school (although they spent much of their lives in schools anyway).
