I've been working on this terrarium off and on for the past month. I've actually had the aquarium since the July aquarium sale at Petco. It hasn't been cheap, but it sure looks nice and is a nice part of our living room too. My wife has never shown an interest in this hobby, but she was taking photos to show her friends today!

It's a 40 US gallon breeder aquarium converted into a terrarium for the Golden Poison frog, Phyllobates terribilis. The dimensions of the terrarium are (LxWxH) 36x18x16 inches. It's hard to find a stand for this size terrarium. I got this one from DrsFosterSmith.com. The other nightmare was getting a lid. In the end, I purchased a versa top and chopped 2 inches off one of the glass pieces. I used my own hinge (more transparent than the one that comes with the versa top), and threw away the plastic gap piece that comes with the top. I made my own vent (about 3 inches in width, and the whole length of the front of the terrarium). The vent keeps the front glass 100% clear of condensation. There is a mistking system with 4 nozzles that goes off every 3 hours for about 5 seconds of misting. This keeps the humidity up while the vent allows a lot of ventilation. I learned the "big vent with misters" trick from seeing Brooklyn Dart Frogs' Andy Grossi's terrariums in NYC. I drilled 3x 5/8 inch holes in the rear (uncut) panel of glass. 2 holes for misters (2 nozzles per bulkhead) and 1 hole in the corner for the heating cable and thermostat probe.
The lighting is a 2 tube T5 HO 78W fixture. The terrarium is located in the living room, which gets a little colder than the temperatures I'd be comfortable with for the frogs. Also, T5 lighting generates very little heat, unlike other fixtures, so the terrarium is heated by a hydor heating cable in the upper layer of the substrate, and the heating is monitored by a thermostat with a probe inside the terrarium.
There is an eggcrate false bottom hidden by a wall of gravel on both sides and the front. The background is tree fern panels with some cork bark pieces (large hollows at the back of the cork bark were filled in with Great Stuff Window and Door). The tree fern is attached to the wall of the terrarium with aquarium silicone, and the cork bark is attached to the tree fern in the same way.
The large piece of wood in the middle of the terrarium is Malaysian Driftwood I've had for over a year. The terrarium has just been planted so it's a little sparse. It will grow in quickly though with that nice lighting. There is a pond on the right hand side which is for future tadpole deposition.
The substrate is a base layer of coconut husk, covered with Ron Gagliardo's Atlanta Botanical Gardens mix (ABG). The leaves are Live Oak. I will probably add some more leaves.
The whole thing was finished on Saturday and I added the frogs the next day (I've never had an issue doing that with dart frogs). There's a lot of growing out to do and probably several more plants to go in there, hence the slightly bare look. This evening (Monday) I noticed 3 frogs up to no good in the coconut hut on the left of the terrarium. They're a little young yet to breed (13 months) but I'm keeping my fingers crossed. The photo was taken just before lights out, hence why the frogs aren't visible - they've gone to their sleeping places for the night.
