Nah, my money is my money, his is his. We've already kicked out a flatmate to give me a fish room so I'm only allowed 1 tank outside of it. I don't think that's fair... we could have one in the kitchen [who uses microwaves these day anyway - right?] ... 5 or 6 in the living room [i like sitting on the floor] ... A few in the hallway.... [walking sideways can be fun]...
