I am in the process of building an enclosure for my Chinese Water Dragon and at the bottom i have a 55 gallon aquarium which i plan to add fish and plants to. My problem is that i want live plants in the tank but I cannot decide how to light the aquarium. The top needs to be open so my lizard can go swimming, so is there a way i can suspend a light above the aquarium and if so what kind of light and how high can it hang. Ideally it would hang well over the aquarium so my lizard cannot jump on it and burn himself.
