Adult tank.

[-MARWOLAETH-]

I'm planning for when my marcianus reaches adult size (wont be long he's a right greedy guts:D).I need you'r advice,I'm thinking about getting a vivexotic http://www.vivexotic.co.uk/products.html.i would like to get him the on that measures 36"L X18"L X21"H but would that be to big for him?Or would the 36"X15"X16 be a better size for him?(I'm not 100% sure on the sex though)

No tank is too big. You just have to make sure there are enough hides. Garters love big open spaces.

There is no such thing as "too big" and the difference between those two isn't that big. If space wasn't a concern, I'd have the largest enclosures I could afford.
