I used to keep gerbils but I’m in the U.K. I’m not familiar with niteangel.
When having gerbils, they’re better off in same sexed pairs or groups. You would need a big glass tank with a secure lid. Anything plastic, they will just destroy. We used to keep ours in a large glass tank filled with wood shavings so the could burrow and make tunnels but you don’t have to use wood shavings, there are other options available such as paper based substrate.
Gerbils are very clean, we used to freshen ours up daily and give them a full clean every two weeks or so.
As mentioned, anything plastic they will just destroy so wooden toys for them to gnaw is a better option
