Using succulents indoors, although nice for pictures, will result in diseased plants that grow long and leggy. Succulents need to be outside and get plenty of air circulation (to avoid fungal diseases and pests like mealybug). They need plenty of light too or else they will grow thin and leggy. If you do this, be prepared to swap in healthy plants every 3 weeks or so.

If you do this, use houseplants for your own sanity.

In regards to succulents, they need air circulation, so an enclosed terrarium would not work. They need light and air, neither of which they will get while enclosed. Also, they would be susceptible to mealy bug.
