Norm makes an excellent point, there is so much talk about our primary fish that we tend to overlook many others.
I live in an area where any warm water fish would be at home. So it is little suprise that Thailand is a large producer of tropical fish, most all of which I could introduce into my pond. We have species from all over the world. However, with the exception of carp, tilapia and catfish, little that is available to you, is available to me. I have angel fish, rohu, pacu, silver barb, red tilipia, nile tilapia, oscar, giant gourami, albino catfish, common carp, jullien's golden-price carp, transverse-bar-barb and golden belly barb along with an assortment of unk. fish. I visited the government hatchery at the end of the season and, without my knowing, they gave me a a little of what was left, most of those above. Several have spawned. I guess that I could worry about them escaping into the ecosystem, but the walking catfish and snakehead fish would probably rejoice.
When you really get to looking there are so many more animals involved than fish. I had a 3' monitor lizard show up yesterday.
