I prefer tubs because ball pythons just seem to thrive in them more than tanks. Tubs hold humidity and heat better than tanks, they also provide a more secure habitat for the snake. Another thing is their food response seems to be 100x better and tubs mimick their habitat in the wild. Nothing against tanks but I can’t stand when people make like keeping them in tubs is cruel. IMO they are way happier in tubs compared to tanks. I think the branches and jungle habitats for ball pythons is more for our pleasure than theirs. Trust me if they weren’t happy in tubs you’d know it! Again nothing against tanks just sharing my opinion especially for the ones that are anti tubs.
