I agree with Eric Alan. As you get more and more animals it not only becomes inconvenient for you as the keeper but also the animals because it takes more work to provide the most optimal husbandry. Figure out what works best for you as well as your current/future animals.

IMO racks work best as they provide an environment that we can fine tune for our animals, have good security, take up less space, while also offering easy cleaning and access.

Good luck
