wanted to add one thing! about baby!!!
which she is absolutely adorable!!! when you know she is teething... just get a clean washcloth get it wet and throw it in the freezer for a while.. then let her chew on it... that helped with my 3 A LOT!! i remember one of them walked around with the cold cold cloth hanging from their mouth as they walked around and chewed it! LOL
also.. the tank sounds great! i bet it will look awesome when you get it done!
