Recommendations for a coldwater tank?

Well if you mean cold water you mean room temp without a heater? I would recommend the Heterandria Formosa the smallest live bearer in the US. They have been kept in one gallon containers and I keep a colony of 10 in a 2.5 gallon tank with live plants. These guys are tiny, and like cool water, i mean 60-70 basically room temp.

I have a list of coldwater fish from about.com, does anyone know much about these fish ad their availibility? Which ones would be best for a small tank?

Barbs
Bloodfin Tetra
Buenos Aires Tetra
Croaking Tetra
Hillstream Loaches
Pearl Danio
Weather Loach
Wimple
White Cloud Mountain Minnow
Zebra Danio

I have seen Zebra Danios around, but that is about it.


Thanks,

Well whatever you choose, I'd choose just one specie of fish rather than multiple species because you dont have the room to mix fish. Naturally peaceful fish would be turned into territorial fish in this setting. IMO, I would pick minnows before zebra danios.
 
I have a school of white clouds in my unheated 30g, and added a pair of paradise fish. The paradise fish really steal the show, mating displays, vibrant color, elegant fins and body shape. Two would probably be a pretty big load for a 6 gallon, but if you go with a bigger tank they are very nice and fun to watch.
 
White Clouds are a great cold water fish. In a 6 gallon I wouldn't put more than 4 or 5 of them. I keep 5 in a 10 gallon and they are great fun. Very colourful and hardy. They do best in temp near 70F but can go as low as the high 50's for short periods of time. Not picky eaters either.
