Is the nanocube stand stable?

[misskeeter2766]

I just got a 12 gallon nanocube. I havent taken it out of the box yet, because I don't have a stand for it. I was looking online, and the nanocube stand looks tall and skinny... I was wondering if it will be stable enough?? I have a two year old, and I don't want her to be able to push it over or anything!!!

any suggestions?
