About a month ago I switched my BP from a tank to a tub. I used to wonder the same thing about tubs, since they're so ugly and tanks really showcase the animal. However, all I was showcasing was a snake stuffed into a hide, like SatanicIntention said. Plus, I was using heat lamps which were making her miserable. She used to get eye dents all the time and never came out to explore, even at night on feeding day. Now she is much happier and healthier with the tub. For me, I can't afford a nice custom display tank, so tubs are the best and healthiest option for my snakes.
