I must say I've never seen a big corner tank on sale when I dropped into
fish store in the USA but they are not uncommon here in the UK with any
specialist shop having at least one on view.

Insulation is not a problem. You put a background behind the tank & stick
styrofoam between that & the walls.

My only concern with these tanks would be the close proximity to the walls
on either of the angled sides ... I suspect this would affect the water
temperature, especially in cold days ... and cold days in Canada are quite
frequent 8P
