Lol same dilemma i'm facing too, love both and i will probably get both lol

However.... Sauvagii are not available for more then a year in Canada, anywhere so im thinking OP is talking about bicolors. If that so, you better get milks, it will be easier to care in Ontario. You wont need additional heating, only humidity, but you have tons of that goodness in where you live. Also if you get milks that recently are of the water from one awesome breeder in manitoba, they will be healthy, cb and easy to care. Tank size you will need for 3 is considerably smaller then you need for one bicolor.

As for me i think i get waxies ( bicolors), they are for advanced keeper, and need huge enclosures. Im not sure of what i'm gotta do, but i think i will go with 42"x18"x76" or similar for 2-3. Or may be even bigger. These are 4-5" monsters with about 10" leg span when climbing.
