These wild-type fishes are intriguing. What is the avg. lifespan for some of them? Are they "friendly," like splendens kept as pets? I saw some of these different species at MN Betta Shop (mnbettashop.com) when I visited earlier this month; the muted tones are lovely, like the "organic" notes of fine wine (I would guess). The quasi-natural, planted tank is appealing, too. John Tullock wrote a book on bettas, fishes and fish-conservation being a great interest of his, and another book on growing hardy orchids, and it seems to me that it takes a similar effort, or sort of effort, to welcome something wild into one's home.
