The tank was designed to allow a 4' photon (German) fixture to sit on the overflow extensions. The fixture had two halides and 6 T5s. The position of the halides was moved to the far outside edges of the the fixture which provided most of the light for the two sides of the tank. The fixture was wide enough that the T5s filled in the remaining parts of the tank.
If the tank isn't going to be viewable from all sides anymore I would suggest moving the overflow box to the back so you can light the tank easier with a standard 4' fixture.
If you can't move the box and you're pretty handy I would suggest building a fixture which uses either halides or LEDs. Two halides will not be enough, and T5s alone won't be ideal either.
