....you fall awake in the middle of the night, can't get back to sleep so you get up and check your fish forums to see what's going on while you were sleeping.
....you still do a head count of your fish just to make sure you didn't lose any while you were gone.
....you start setting up tanks at work because you've run out of space at home.
....when you click on your favorites menu, they all seem to be fish related.
....you look forward to getting home just so you can see your fish because you missed them.
....when you shop in the fish department of an iffy store like Wal-Mart, Petco, or Petsmart, you eaves drop on conversations other customers are having with the salespeople to see if they are being told the correct things to do and if not, you immediately rush over and offer your expertise.
