I noticed nobody replied to you so I'll try and help you out. I'm also new to Dart frogs but I can say that they are not as hard to keep as you might think.

First off, Hyla cinerea and D. auratus are completely differet types of frogs with different needs. PDF's require high humidity and temperatures in the mid 70's, whereas reasonable airflow and a screen top is sufficient to cover the top of your tree frog's enclosure. Also, you mentioned the Auratus were eating crickets. Pinheads are fine but you will also need to learn how to raise fruit fly cultures along with several types of Isopods. Dusting your frog's food with supplements is important. I dust my fruit flies with Repashy Calcium Plus daily and then use a 50/50 mixture of Herpa Vite and RepCal three days a week.(This is a supplement routine I got from a PDF pro.)

As far as a lighting I believe 12 hours on and 12 hours off is the standard time schedule. For frogs a 2.0 tube or CFL is okay but if you are going to have a heavily planted tank then a bulb with a high K rating(6500) will be needed for decent plant growth.

I would suggest researching and reading a caresheet for this particular species of frog. I hope this helped a little and maybe someone else can add to this or correct me.

Good luck.
