Hello. Recently, I've been very interested in Dart Frogs and am willing to take on the challenge of creating a cool vivarium to house a couple! To start off, I know not to mix species and I'm lucky enough to live relatively close to many vendors and reptile and amphibian shops! I already have a nice 18x18x24 Exo Terra tank that I have previously used to house different types of small geckos and frogs in the past. I know to clean them out thoroughly, but all tips are welcomed as I'm still a novice to Dart Frogs.

First off, what species would be recommended for starting out? A friend of mine told me told me the green and black ones are fairly easy to maintain and that he has had 2 for a couple years now. Also, what type of lighting would be recommended? Would I need one of those fancy humidifiers that many vendors at reptile shows say are very useful? I also wanted to keep 2 frogs. I've heard that is about the max you want for an 18x18x24 tank. I've watched a few nice youtube videos and guides on setting up vivariums and have a decent list of supplies needed. I'm very interested in building a waterfall, but obviously I want to make sure it is safe for the frogs and nothing can happen with them climbing in it or anything. Live plants or fake plants?

Lastly, I'll be attending the Reptile Expo in White Plains, NY on February 8th. What types of questions should I ask a vendor there?

Any answers really help and are greatly appreciated!!
