Thanks.

I got a spider plant and a peperomia ginny.

Peperomias seem fine according to this general article, but I don't know if it can be trusted: Plants for Terrariums With Reptiles and Amphibians

Any thoughts.

I also found compacta janet craig (a dracaena). Someone recommended dracaenas in another thread but they seem a bit harder to care for or more specific in their needs. Also is it hard to keep their size under control (will they eventually outgrow a terrarium)?

I guess that last question also applies to the peperomia since I don't know these plants....
