I started my 100 gram boy in it. It'll be plenty big until your snake gets to be almost 1000 grams, then you'll want to move a female up to a 41 qt. That's a long ways away so that tub should hold you over probably until you feel the need to buy a rack. If your snake is acting stressed (constant roaming, not eating) then you can ball up some newspaper and put it around the edges to clutter it up.
