Hey people. I got 4 apple snails - Huey, Duey, Louey & Stuey, presumably Pomacea in November 2005 and put them in my outdoor pond in Auckland. There, they have been happy all summer, mostly eating red plum leaves that fall in the pond. They have grown, but are still more like golf than tennis balls.
My question is... knowing that the temperature of the pond is dropping quite quickly now, am I at risk of losing them to hypothermia? I've thought of sending them on vacation to a friend's indoor tanks, but hearing how large their apetite can be in warmer water, I wouldn't like to impose.
I guess another option would be to try and warm the water a little. The pond is about 80 gal and 10 metres from the nearest power supply. Any ideas?
Thanks in advance .....
