I have had both, tree frogs and I am currently keepings darts. Most tree frogs are nocturnal while dart frogs are diurnal. I used to keep Red-Eye Tree Frogs and when those males started calling at 1:00 in the morning it would drive me crazy.

Dart frogs are so unlike any tree frog or toad I have ever kept. They exist so perfectly in the artificial environment that you create for them. This is why it is important to do your research and learn the proper way to create their enclosure and not skimp on anything. Before you even think about making your first purchase of anything be aware that this animal is going to cost you some money. The frogs themselves are expensive but all the individual components can really set you back. You don't have to get fancy with the vivarium it's just that there are quite a few things that go into the construction.

Do your research and don't rush into it. Remember that you need to let your vivarium grow in for at least 4 weeks. I have two Exo Terra's that I built up about 5-6 weeks ago in anticipation of some thumbnails that I still haven't bought yet. I'm still tweaking both enclosures, adding plants and moving bromeliads around trying to get them into just the right spot.

Fluffysmom really pointed out something important to remember...you are going to have to learn to culture fruits flies and some species of Isopods and springtails.

Don't become intimidated with the thought of getting into darts. You just need to learn how to do things the right way --- Good Luck!!!

One last thing. I noticed that you live in Sultan, Washington, which is just outside the greater Seattle area. For some reason there is a huge amount of dart frog breeders in that area. When I first started researching dart frogs that was the first thing I noticed, the large amount of individuals that kept and bred dart frogs. You'll have a really good support system and have close access to frogs and supplies and help.
