I am currently building a "picture frame tank" - it will only be visible on one side. The tank will sit in the garage in a "fish room" that we built (with its own air conditioner

) You will be able to view it from the living room side only.
I will post some pics as we progress.
The key is to at least be able to put one side against a wall and then have some sort of "fish room" on the other side of that wall (even if it is only on one of the short sides of the aquarium. From what I hear it gets too crowded to try and fit everything underneath....I am pretty sure there is a thread with some photos from someone who jst did this - I'll try to find the thread....
