It's a beautiful little glass tank, however it is NOT a terrarium. I filled my "terrarium" with two carnivorous plants last night, and when I opened the lid, it broke off. No big deal - I figured I'd just leave it open and remember to mist my plants (rather than let them get the natural humidity that a terrarium typically provides). When watering my plants, that's when the real issue was discovered. This Glass tank is NOT fully sealed. It leaked dirt water all over the place. It's pretty, but despite its name DO NOT USE IT AS A TERRARIUM.
