I am lucky my wife actually got me into the hobby, and when we were looking for the house we just bought our realtor was a reef friend so every house we looked at started with "Ok so where would the tank go?" lol. I guess I lucked out.
I ask every now and then if she is anoyed by how addicted I am to the hobby (I am keeping my apartment an extra month to make the tank move easier,etc) and she says she is just happy to sit back and enjoy the fruits of my labor as she was never able to keep such an amazing tank before. She even had the gall to tell me that our new 150 gallon tank was too small and we should get a 300 gallon, lol.
