my mum went down the route of having guppies and mollies which she chose for her boyfriend, but apparently she has no interests in them! haha at least your wife picked cool fish
I find my self stairing at them all the time. We have 2 of them in the living room and one by the computer. Wives are not to bad if you get them involved. I learned the hard way though do not let them buy fish for your tank though. Mine likes the prety colorful fish so I let her have my old 55 to make an african cichlid tank. Can't get her to clean it, But I get to keep bank rolling my obsesion
