FW snails in Calgary?

[allincuddy]

If your out break is on the glass, (actually anywhere) I wouldn't go with snails, but get yourself an albino bristlenose pleco. Thet won't harm any fish and are the hardests workers as far as removal I have ever had. I have been doing fresh water for 12 years and have 2200 gallons basically for breeding. I have a BNpleco in every small tank, including ones that have 1 day old fry in them and they don't touch any fry.
I don't know much, but this is a for sure.
Thanks.
