I'll try to get some full terrarium pictures. As for climate control I simply seal the tanks up completely and put the lights on timers. Temps stay between 70-75 degrees, and humidity is 80-95% depending upon time of day.
What are you feeding them? I always had problems finding food that mine would eat
My frogs greedily eat both Melanogaster and Hydei fruit flies (which I raise both inside and outside the viv). They also graze on the tropical pink and tropical white springtails in the tank (especially the Ranitomeya sirensis), as well as the dwarf purple isopods. I had some little flying gnats come in on some peat moss in the 75 gallon terrarium, and the Ranitomeya sirensis seem to love those as well.
I just built another terrarium, a 30 gallon. Trying to decide between Dendrobates tinctorius "citronella", Ameerega trivittata, Ameerega bassleri, Ameerega pepperi, or Dendrobates leucomelas.
