Its hard to say the favorite because they are all unique and have qualities that I enjoy.
So here are my favorites:
1. Favorite Tree Frog- Red Eye Leaf Frog, you can't beat them for their grace and beauty. They do well in groups, you can get yellow or green ones. They wont eat you out of house and home. Easy to keep.

2. Favorite PDF- Cobalts- They are bold and active all day long. They interact with each other and are great frogs for a display tank. Very easy to keep.

3. Favorite Thumbnail PDF- Veradero-What can be more fun then a bright red frog with black racing stripes? They move around the tank all day. Easy to keep.

4. Favorite Breeder- E. Anthonyi Santa Isabel- They are the easiest frog to breed. They just do it. It is fun to watch the eggs develop and dad protect them. The dad will sing from the top leaves and then transport the tadpoles to water when the eggs hatch. Its just amazing. Very easy to keep.

5. Favorite feeder- Fruit Flies- They make themselves really easy and they are practically free. And they don't stink like crickets.
