Thanks everyone for the very enthusiastic replies! I myself am barely able to resist the compulsion to take the day off and go aqua scape shopping so that I can move the fish in ASAP!
shellbell4ever: the tank's dimensions are 24"x12"X16" so I *think* its a long tank. All the blue is from the fluorescent lamp. I asked the lady and they said it was a 'white' lamp :/ The blue color is somewhat increased because of the blue plastic borders on the top and bottom of the tank.
JESS01: me too!
Lucy: to answer your questions:
1. The light fixture is just an aluminum housing placed on the glass lid of the aquarium. It can be easily removed during cleaning and water changes.
2. The tank has a simple glass lid on top. I'll attach pics later when I get back from work.
3. Ah! Am always glad to help a fish lover rationalize a need for more shelf real estate!

The "shelf cabinet" was originally used for books/sound system/TV. The larger area where the 20g tank is now is the area for the TV. You can see in my
original post that the left side used to be full of shelves and books! So one key aspect of this shelf cabinet is that is customizable, and the shelf planks can be removed!
So whenever I do water changes, I just remove the books and whatnot on the shelves over the tanks, and remove the shelf planks! Voila, easy access to tank. I remove some stuff on the topmost shelf to put the pail from which I siphon the new water.
Had I been able to get a 30gal tank, I would have moved all the stuff from the top shelf and put it in the TV area and put the tank up there. Then during water changes I would use a power-head to pump the water from the pail on the floor to the tank up top.
Cheers!
