Will a pair of thumbnails......

Oh boy, where to start. A water feature in a tank that small will be a tight squeeze because you don't have a lot of floor space. I have one set up with a water feature in it, a large piece of mopani wood set in the back wall of great stuff. The pump for it is external though, I had bulkheads put in the back. Your water height is limited by where the holes are in the front, if it goes that high it'll dribble out the holes. Watch it when you mist, the water level will go up every time you mist. You must have glass cut to cover the screen top in order to get the high humidity you need. I crack mine slightly by laying a pen under one side so the front glass won't fog. If your water feature isn't contained somehow to one area it will soak the substrate, keep that in mind when planting.

Darts like hiding in leaf litter, you can't put a whole lot in if the water feature is too large. I don't like leaf litter so I just cram twice as many plants as humanly possible in there. The rule of thumb is 3 bromeliads for every dart frog. I managed to put 2 gigantic broms in mine (1 high 1 low) and then shoved 3 more mini neo broms in the gs background. That's not counting the 2 orchids, 1 vine, 1 hoya, 1 ivy, and a pothos like plant in forget the name of and the 2 water plants I put in the pool at the bottom. If the frogs can't hide in all that they're just going to have to stick to the glass.

If you set the background up right you can put a lot into a 12x12x18 but I had mine made by a local very experienced viv builder. I don't have the tools to drill the glass and I'm all about the gs mess in his garage and not mine.

Vitamin supplements, very important for darts.
Reptical
Herpavite
Repashy Calcium ICB
Repashy Superpig (twice a month)
Vitamin A (human grade, dry, from Amazon.com) twice a month

The first three I use everyday that I'm not using the last two, 1:1:1
The last 2 are for coloration and vitamin a which most dart frogs have a serious lack of. There's warnings of overdosing them on vitamin a, that's why they are only once a week. I feed the vitamin a and superpig on alternating weeks. The schedule depends on you, everybody is slightly different. Almost everyone uses the first 2, not everybody is enlightened to the vitamin a. I add the ICB because it's sweet, the frogs love it.
