No such thing. Put the new tank in a room you do not need as much as a new tank. Like the kitchen or bathroom
Don't think that the wifey will go for a large tank in any room other than the living room, but that would be awsome.
This whole thing went from me wanting a small seahorse tank, and she suggensted that I ugrade to a larger thak and use my 37gal as a seahorse tank. Of coarse, she said to do this when we buy a larger home....hehehe....not waiting that long.
I actually don't like the larger speiceis of fish, I would perfer a lot of smaller fish, like a school of chromis and 2 clowns, but we will se. I am heading to my LFS
to see what size tanks they have.
If I go for an upgrade, its going to be like 4 month process. Gotta cure a lot of rock before I can evem make the move.....
