LOL!
Ooh, that's a nasty joke to play on someone!
I recently visited a customer's home and she had a "reef" tank. The tank was about 40 gallons and had a Sailfin tang, and about 7 other fish (the poor tang was just swimming laps in distress, apparently there was another tang in there too that she had to give away when it went crazy). The reef part consisted of reddish brown shrooms, GSP, and the most enormous aiptasias I have ever seen, covering every square inch of rock. Since she was a customer, I wanted to be nice and say how it looked nice, and I was thinking I could hook her up with some other low light frags, but I knew with those aiptasia, there would be no hope for adding anything else. I couldn't hold my tongue when she pointed out her Coral Banded Shrimp, and I said " maybe you can get some peppermint shrimp too, to take care of that aiptasia". She looked completely puzzled, and it was then that I understood that she liked the aiptasia. Oh well! So much for being nice....hopefully she didn't notice as I quickly derailed the conversation to something else.
