Can whites tree frogs see red light? I bought a flukers incadescent red bulb for night time viewing thinking that amphibs can't see red light, but i noticed my frogs pupils were constricted and he wasn't moving much. All day he sleeps and doesn't move at all (which i figured cuz they're nocturnal) but at night i hear him bouncing around the entire cage. I just really wanted to watch him interact in his environment. Did i just waste 8 bucks?
