Wewe--Yellow Striped Goatfish

This little guy is a bottom feeder. He uses his whiskers to stir up the bottom to morsels to eat. In the words of wiki:

Yellow goatfish are tireless benthic feeders, using a pair of long chemosensory barbels ("whiskers") protruding from their chins to rifle through the sediments in search of a meal. May grow up to 39 centimetres (15 in) in length. They usually feed off of smaller fish, hunting in a school during the day, and alone at night.
