Hi I was just wondering if there was any kind of Amphibian light where I can see my two Gray Tree Frogs but they cannot see the light. I know they like it dark all the time and your supposed to keep it dark in there terrarium, but I just hate having to turn on the light and get them all mixed up just to see them. Also I do not know whether I have two males, two females, or a male and female.. Thanks! The first 5 photos are the first tree frog, and the ones after are the second one.
