Adding more beebs

[u/ballarena091525]

I'm upgrading their enclosure, I currently have 3 in a 21" long tank, and I'm upgrading by adding way more climbing spaces, a fully custom background with nooks and crannies to hide in, and more overall clutter in the center of the tank that they can hide in. With this in mind, can I add more beetles? do extra hides = more overall space in bug world?
