There shouldn't be issues with hobbyists keeping their animals in tubs either. Snakes are a hobby for me and I keep mine in tubs because that is what they are happy and thrive in. They don't just have a shoebox and water bowl either. Yes, they do 'lie around' all day, considering that ball pythons are nocturnal, so actually sleeping. But at night they are very active.
Also, ball pythons are the limit to what I would feel safe housing in tubs, anything bigger has to be in an enclosure with a lock and key, no exceptions.

That makes me mad too, people breeding snake morphs that have known issues, in particular the spider gene. I will absolutely never own a spider gene snake and deal with the wobble. A champagne however....trying not to give in, its one of my favorite morphs and I love anything with champagne in it, I'm not buying one though.
