Advice for a newer owner

Hey there! Have a paladarium (12x12x24, pictures attached) and kinda just wondering what to do with it, or what to put in it.

Currently, there is 3 nerites to clean, and was kinda just wondering what to do with the land or what to put in the water, about 80% land 20% water.

Any advice, plants, animals, maintenance (misters are not connected just filter and pump, holds humidity great!) would be appreciated.

I don’t have any current pics, plants are much more grown out after a few months.
