Terrariums

I have an empty 15 gallon tall fish tank. I want to turn it into a terrarium. Nothing underwater. Was wondering if anyone had any ideas as to what plants to put in it. TIA!

At the bottom right, there is a new Polkadot Plant that went to root from a clipping while I was cleaning up overgrowth.

When I've clipped Polkadot Plants and take them out of the terrasium, they usually wilt in minutes. I clipped this one and left it on the soil for springtails to eat on. I guess its going to grow instead!

I ended up trying this mixture of soil: https://youtu.be/jaitvmFrws0

What works well for you?
