Ideas of what to do near spare room? It's going to be me (21) and my boyfriend (25) moving into...

It's going to be me (21) and my boyfriend (25) moving into a big 2 bedroom apartment.
We're taking one room, and what should we do with the other?
We've get 4 fish tanks, a laptop, a desktop, /i don't know if we should enjoy a computer room, seems boring to me,
or a relaxing room beside fish tanks? but what else?

it seem a bit blah.

the fish tanks could travel n the living room and in our room

i purely wanna do something funky or exciting with the spapre room.
we're not rich lol

any concept please??
Answers:    How strange ...I was going to suggest a "Quiet" room beside an Aquarium ...cozy furniture...bright colors....maybe plants? (depending on the light)
Hey...you already hold the Aquariums ;)
*be careful ....sometimes when we do change to a room ... it ends up being a nursery ;)
this happen to me years ago...I had made a spare room into my "Painting" room (I paint w/oils) it be a dream come true. It also turned out to be a pretty neat nursery as capably ....just months subsequent.
Rent it out. Get another room mate.
