The glass vase is about 1/2 a gallon (about 1.8 liters) so it's quite small. The light is a simple 8 watt compact fluorescent flood light I bought at Ikea (it's not really the right color temperature, but it gets the job done). There's no filtration, since doing water changes is so easy and there's no livestock except a few Malaysian trumpet snails.
It looks rather barren now, but it should slowly but surely fill in. The plant in the back is a narrow leaf Java Fern, the front left is a dwarf Sag and the front right is Stargrass. There's also some Christmas moss tied to the rock and a little leaf of hydrocotyle on the far right. I think once it gets established I'm going to move in a few cherry shrimp to add some color. The total cost of this nano aquarium was about $20 for me, but would be about $50 for all materials:
- $15 for the bulb and light
- $20-30 for the vase (I had it on hand)
- $5 for the substrate
- $5 for plants (Came from another of my tanks)
- $5 for wood and rock (Already had this on hand)
