Water Gardening: different kinds of koi? , 1 by HoosierGreen

A rock bubbler instead of a waterfall would work nicely, and look great too. Basically, you could just pile up some rocks in the new pond and have water "bubble" out the top, cascading down the sides. Real easy, and aerates the water for the fish.

Goldfish are fun, too, instead of koi. And, if a blue heron or other critter gets a few, they aren't as expensive to replace. There are lots of varieties to choose from, and they reproduce every year, giving you lots of new ones!

Keep us posted on your progress.

(Here's a photo of a small fish pond with a waterfall and stream I did for a client a few years ago. The large flagstones were so her small grandchildren could get to the edge safely to feed the fish, and not do any damage.)
