Ahh, my bad on the sizes. I didnt have a tape measurer with me, so pretty much guestimated. That and the fact that all of my BP's are in tub enclosures but yes, your BP should be fine in a 32 qt. tub or 20 gal long tank. I have a friend that has a year and a half old, 1000g+ Female that is still in a 20 gal long and is doing just fine.
