Why is this considered acceptable?

I think it has to do with understanding the natural history of the animal. A monitor are active hunters in the wild where as both ball pythons and green tree pythons are sit and wait ambush predators. That is why both species of snakes can thrive in a smaller enclosure than what you may think is acceptable for a snake their size. In the case of ball pythons people think they are notoriously finicky eaters, but I think this mainly has to do with husbandry because people who have been in the hobby for a long time seem to have less problems. Most people obsess about temps and humidity but ignore that ball pythons must feel secure. Ball pythons spend a good amount of their time crammed into small spaces. When being collected they are most often found in termite mounds and require a good amount of diggind to get them out. I agree if the animal thrives than who are we to say which method is best as we are all mostly hobbyist. On a side note that tub does look awfully small for a snake that size.
