Building a friends tank

I've got a friend in the surf industry (Surfboard Warehouse, HIGHLY reccomend him for all your surfing needs, great honest guy) that wants to get a tank for his office. He's low on money now so nothing happeneing soon but, he says when he gets the money rolling in, he wants an 8ft by 24" tank. I'm loving this. Its like building a dream tank, that doesn't take any space in your house!

No idea when this'll throw down but it would be an inwall tank which would be a blast to design.

I'm thinking 8ft x 2ft oughta be able to keep 100 chromis right? lol
Nah we're thinking triggerfish/puffers/damsles/etc no corals.

That's soooooo cool!
