Made this cute terrarium a couple weekends ago and I'm just wondering what's in it? I forgot to ask when I made it and want to make sure I take care of it properly. A little concerned about the tiny dark green striped ones near the bottom already looking wilty a bit. To clarify, forgot to mention, it was made at a plant shop in Nashville, TN, unsure if that makes a difference but that's why I don't know the names (didn't buy them individually myself).
