Some ball pythons don't care if it's identical or not, but if one prefers a specific hide over another then it's advised to get identical ones. That way the ball python isn't choosing it's favorite hide over it's thermoregulation needs.
It's not a requirement, but I would personally advise using identical ones just to avoid favorites.
P.S. People are often rude when they are argued with. When they give friendly advice first, then the rudeness comes when the OP argues for some reason or other. Sometimes though, it's because we deal with the ignorance of people who ask for help but refuse to do the right thing for the animal. We get a lot of reoccurring issues and we don't mind helping and answering questions but sometimes the irresponsibility of some owners can take it's toll on us. Don't take it personally.![]()
