They'd all get their time to go run around outside, have a meal, take a bath, etc but realistically nobody is going to have room to comfortably accommodate hundreds if not thousands of creatures with a wide variety of needs 24/7 365, so putting them into stasis with a shared virtual reality where they can play together and do whatever makes them happy when it's not their turn to come out of their ball/box would make them manageable. That way a bunch of trainers collectively owning 30 wailord doesn't require every professor or whoever to own a private sea to safely house them all, just 1 or 2 giant tanks in the aquarium part of the facility they can take turns in. It'd still require funding and resources few individuals could acquire, but is a lot more feasible for a researcher and their team to cover with grants, book sales, and donations.
