What's the view on using aquarium decorations? I'm talking like the sunken ship type thing, or the cool rocks with holes. I'm getting a 90 gallon and I was just wondering like how I could fill all that space. I really need some ideas!! And seriously, I've asked this in other threads but no one seems to answer, how do you make a scale drawing? My room is 114"x134", so how would I figure out how many inches per inch if it's going on a 22"x28" poster? I'm trying to figure out whether I can actually fit the darned thing in my room.
