A few hints from my experience with darts:
1. If your just starting out, simple set-ups are better. Work your way into the more complex terrariums. Frogs don't need water features etc, they are more for us.
2. Have your temps dialed in before you get your frogs. Even the most modest lighting can make a sealed off glass terarium too hot for frogs.
3. Don't run out of flies! It's easier to do than you think. Make extra cultures. Dust them regularly. The general consensus on supplementation for frogs is usually alot more than chameleons.
Thats all I can think of right now.
