Take A Break New Year's Special, Puzzle 1

[campbellking]

Am struggling on this one (have decided I don't know enough about sea life).
Pair up the following words, and the one left over is the answer.
Dory, Conger, Trout, Skate, Bream, Queen, Lemon, Eel, Red, Sea, Skipjack, Prawn, Lobster, Snapper, John, Scallop, Rainbow, Tiger, Rock, Tuna, Sole

Am assuming John Dory, Conger eel, Rainbow Trout, Red Snapper, Skipjack tuna, Tiger prawn, Lemon Sole, but then I get a bit stuck.
Thanks
