It's a cool thing to try, will be conclusive either way.
I would have thought it might be better to start with a juvenile fish though, how old is your fish? Are you planning on any special,feeding techniques like in the above posts or do,you think the rock alone will do the job?
Sorry if dumb questions but I'm not familiar with this fish and find this experiment genuinely interesting.
