hey avs
remember me from RC?
well the frogs dont really need running water, misting the system daily will keep the tank moist enough, and unlike chameleons they dont have to drink from a running source, as long as you can keep the humidity in the terrarium high you shouldnt have problems.
your lighting is good, remember plants need the lights, but sometimes frogs dont like intense lighting (unlike reefs). as long as the light keeps the plants happy it will be fine.
As for auratus, they are great frogs, but they can tend to be more shy (some people here will say they are extremely brave). from my experience they were extremely shy. There are plenty of good "starter frogs" (which include auratus). look into the different species. i reccomend dendrobates auratus, dendrobates tinctotious, dendrobates azueres (although they can be pricey), dendrobates luecomelus, or phylobates terribilis (these are the ones you saw on reef central, eventually they will turn completely white).
shy away from the so called "thumbnail" species such as D. pumilio, D ventrimaculatus, D reticulatus etc. they are MUCH smaller than the previously mentioned frogs (hence the name "thumbnail" since they get about the size of a human thumbnail).
browsing through this forum gave me a bunch of good ideas for my vivarium, so flip through some threads you will definitely like it.
