Spires,

There are a couple good how to guides for setting up a dart tank in the vivarium section of the forum. If you haven't already I would go read those for some ideas on how to tackle some of the basic setups.

The tank size is a bit on the small side. I wouldn't put more than 1 maybe 2 frogs in there. Once you factor in the false bottom/Drainage layer + soil the tank will be 15 - 14" tall and if you do any kind of a 3D custom background you will be looking at roughly 8 - 9" deep. If you did anything to the sides you would be shrinking it even further. You could probably keep a couple of thumbnail darts in a tank that size. Just somethings to keep in mind as you look into the frogs you want vs your enclosure.

Oh and Welcome to the Forum!
