People are nuts spending that much on a fish. You'd have to be very confident in your abilities to keep it alive and hope nothing gets to it (disease, another fish, power loss, etc.).
I guess if you have that much money to burn then the "look what I have that you don't" factor/attitude kicks in with these people.
Hope whoever gets it has good luck with it.
Oh yeah, remind them they'll need to get another so they can start their own breeding cycle. (Maybe they'll luck out and start a new lightning strain with another clownfish type).
