But in the end, a pleco is a catfish and can adapt to non-tropical conditions if you go at it slowly.
.... Hey Bush you sure Plec is happy in cold water? They are a tropical fish.
Anybody got plants in the ponds?
I have a pond-to-be that needs a little more digging and then liner, pumps, and so on. Left a couple places in the center where the dirt will be within a foot of the top so plants there and along the rock wall at the back. Remainder of the bottom will be from 3ft to a deep section of 7 feet in case we get a real cold bit of weather and the fish need a deeper hole to lay up in.
Have a nice hill in the back yard and started the pond at the foot of the hill and dug into it so the location for the water fall thing is about 4 feet above the pond.
