I'm thinking about starting a business down here building natural ponds. The two guys that built mine are pretty trust worthy and we now have two under our belts. I have aquatics plants coming out of my ears. Every week I have to throw away about 20% because it reproduces so fast. And to answer your question about the Dovi's, yes I think I'll start selling them with the different projects I do. They to are reproducing like crazy, though most of the fry get eaten. I enjoy my projects so much that I though it might be an interesting adventure making natural ponds and spreading the beauty. I'm not talking about your typical commercial koi ponds. I'm thinking about ponds with close to native fish, animals, plants, etc.
