Terrarium with little castle

Ah, there are only springtails, tiny snails, and isopods (They came unintentionally into the soil).

I used a mixture of cocofiber, moss, and garden soil.

This enclosure is 20 x 20 x 20 cm.. I made it from a regular aquarium + some DIY projects using aluminium, tint and plaster. I wanted it to look like something old, like a "Grandma's inheritance"

I added some plants: Fittonia, Peperomia, Dracaena and Davallia fejeensis

English isn't my first language btw
