Tank size:

How big of a tank will I need for a 3-5 ft. BP? Anybody know?

[takagari]

this has been covered a billion times

but a 30 gallon long would suffice

if u wanted to build
a 4 foot by 2 foot by 16 inch high tank would be great

Yes, you can go with 30 gal for now or go with what you will need when the BP is full size - 50 gal.
