What is the answer to number 29 on the impossible test?

Assuming you refer to the Impossible Test that can be downloaded on to your iTouch, iphone, and ipad, the answer to number 29 is to tap the fish in the bottom right-hand corner. He is the different fish because his bubbles' bit of light is facing the other way to the other fishes'. If this is not the answer you were hoping for because you were asking about a different fish, I apologize.
