Interesting. I can tickle fish, but I never eat them. Cannot stand to even see someone clean a fish. My fish Elvis taught me how to tickle fish. He ate everything, and I do mean everything in his tank. He got so big I didn't have a net to fit him, so had to tickle him to change the water in the tank. He lived 11 years, and was just a common carnival goldfish..Alas Elvis, the King of Fish, we miss you.
