Thanks for the replies. I see what you mean ron, it is awfull risky. Although I can't really think of where else to put them. If I put my fish in the hallway, or in my basement, or pretty much anywhere else, there will be a greatly elevated risk of my irresponsible siblings breaking it.
The only other safe place I can think of is the same room with the piano and the table. I'm guessing this would be better than having it upstairs, but I'm not sure (since I'm not a water leak expert).
I'm not the fishkeeper I should be. I want more, and I know I shouldn't!
