Well, If you grab yourself a nice 250 watt rated lamp fixture, and a nice big household bulb, don't worry about what kind, everyone knows one type of lights just like the other you'll find you can make a great Lighting fixture that will ensure all the invisible anemones in your tank grow really well, They'll grow so well they'll even sting you at the surface of the water..
What you want to do is actually hook the lighting fixture up inside the tank, It sounds crazy, but it insures the tank will get all 360 degrees of light..
While your at it you really should buy a few frags of that green coral off of Coral Keeper, You can attach them directly to the front of the glass so your fish will feel safer while they nap on the bottom of the tank.
