Moving to the lounge, as I dont really know where it belongs.
FWIW, I sometimes thought the same until I read a thread somewhere about fake things in a reef tank. This one lady who was a nurse in a cancer ward, said after a day at her job, coming home to her little saltwater tank, with its fake plants and bubbling treasure chest and so on, being her release from the day or something like that.
It was something that you had to read to put things in perspective. Kind of like one had to be there at the time.
