Thank you once I am sure everything is dialed in and I add the frogs I will post some updated pictures.
I have a light meter already on my list of things to get, my main concern was that dart frogs are generally under a canopy so I didn't want to blast them with tons of light, but I wanted to make sure the plants on the sides of the tank got enough to thrive and grow. The light is a T5HO 5.0 bulb so as far as UV output to the bottom of the cage is concerned I know it is good to go, I just was worried about overall length.
