When planting a terrarium, it's good to remember that some plants (including Fittonia) will grow tall so pruning is really important. As you can see in some of my old photos below, the plants will end up reaching the top the container if not pruned to keep them in check.
The only terrarium I currently have planted up is the old 45 gal. aquarium shown below and the Aglaonema is growing out the top/ I've been saying for many months that I need to either chop it back or remove it and plant something that will stay shorter ... but I'm old and lazy so it's hasn't happened yet.
@Hamwild, a 10 gal aquarium makes for a nice terrarium ... just be sure to wash and rinse it well before planting it up. I still have an old one that I want to replant at some point.
