For your hood/lid problem I have a suggestion.
You can easily cut 2 large pieces of plexi to cover your two top openings.
Some cheep hinges in the back to match your carry handles should complete the look easily. I would also consider a small latch or piece of Velcro on the front edge to help keep in down in case your Arowana decides to jump as I hear they are famous for.
You can then take advantage of your tank being wood in the back and attach some piece of 1" x 2" vertically that is tall enough to support a hanging light fixture over each of the openings. Although clearance from the plexi lid may be an issue. I'm sure you can figure something out easily.
Or the lights could be mounted to the garage wall easily if you can find the studs.
The thin plexi top (1/8"?) would keep the heat and fish in. Some cold out and wouldn't add any undue height to your monster tank.
Hope that all makes sense.
