Sablefish, also known as Black Cod, are enjoying a boom in price as the in-demand fish of the hour.  The Monterey Bay Aquarium Seafood Watch guide currently ranks them as “Best Choice” or “Good Alternative,” depending on where they are caught.  While the adults are indeed black and color (and do taste delicious, from my limited exposure), the juveniles are a rather attractive pearly green, like this one turned up in a fish trawl off of southern California.
