Pothos

You receive the plant without a pot or soil. They are cuttings with 3-4 leaves and roots.

The pothos has established itself in terraristics due to its simplicity, indestructibility, strong growth and large protective leaves.
It can simply be planted in the terrarium and within a few days to weeks it will take root and start growing. 
Within 1-2 months you have a really large plant sprouting through the terrarium, from which new cuttings can be pulled without any problems. The plant can be pruned just as easily.
In general, the pothos is poisonous. But that doesn't do anything to the snails, because they know exactly what it is. So don't worry. 
Last but not least, this has the advantage that the plants not get eaten. Of course, my plants are not fertilized.
