betta fish is also known as a Japanese Fighting Fish, or something like that, they're quite a commonly purchased fish in pet stores they're really hardy, and have these long pretty fins, and come in a whole range of colors (not rainbow) But ya cant stick males together, cuz they'll fight eachother to the death, so you'd have to buy 1 or put each in a separate bowl
I used to own 3, but eventually after some years, they died. They can live up to 3 years or more ya Know :3
Winter Whites are often found on the pet market, in Japan and Europe more so than in North America and indeed are rarely found in pet stores in Canada. Care is similar to that of the Campbell's Dwarf Hamster.
that's from Wiki.. but i think they must be in pet stores in USA)
