Dude! Are Marlin & Dory still working on Finding Nemo? Anyways, they must be surfing the EAC that runs past Australia & New Zealand in the "it's a small world" South Pacific Seas.
Note: After some exhaustive research (and arguing), we guessed that this clownfish was Marlin - because his right fin seems a little too large to be Nemo's. Although, Nemo could have grown a little since we last saw him.
