When to Move to Bigger Tub?

[MasonC2K]

So my spider that I got in July that was all of 52 grams just surpassed the 500g mark. He's in a 6 qt tub and when coiled takes up a little more that a 3rd of it. I know balls like cramped places but maybe that's a bit much.

Is it about time to move him up?

I'd say yes, my female spider is a tad over 600 grams and she fits great in a 12.5 qt tub (my RBI rack...).
