Question: How can you get a pink stickfish to sell? I'm tempted to throw the thing away! It's useless and won't sell even if I leave the game in sell mode for hours.

Comment: A few of you have talked about your oldest fish. I had a twinfin shark that was about 2500 when I accidentally sold it. Somewhere in the game it does say that the Isola fish don't die of old age.
