Fish Fanatic
I think the best thing to do is to write down all the reasons why a new tank would be good and how you could benifit from it, then show her the idea and all the work you did, she will be so suprised and happy at how you presented the idea and glad you didn't just bug her every day about it. If you your lucky you got yourself a new tank. If your not lucky she will just say, "Well I would love to get you a new tank, but there just isn't enough room right now, maybe in a few years." Or "When you move out you can have as many fish as you want."
