I find it funny that so many people come from the reef keeping hobby to dart frogs. Although you still have a reef I have seen countless people post that reeds was their previous hobby. Both of your setups are fantastic by the way!
I Have noticed the population of reef keeping and frogs are pretty high. A lot of my friends in the hobby have both or want both. I just love anything that can be kept naturally in a glass box. Fish frogs, corals, you name it!
