I'm absolutely want one of the aquariums!! I just can't decide if I want the large, deluxe or ultimate! I plan on putting one in the harbor studio and city penthouse. I was leaning toward the large since at my penthouse, there's already a TV and radio which would mean I could only use 35 blocks left for furniture. I figure if I got the ultimate one, I just simply dedicate a whole space to it. Any idea on what space would best suit it? Help me, no matter which decision I make, they're all plunges in my wallet. Thanks.
