Its give and take. What can you give your wife (i.e. chocolate, credit card for clothes supershop, etc.) to make her forget about the large amount of tanks that are going to be strewn about the house?
At one time, my tank in the kitchen had L. Aromatica as a center piece and the tops were really red, so my wife passed the tank one day and said, WOW, those flowers are beautiful. All I said was "Yes Dear" and several years later the tank remains in the kitchen, shhh!!
