Comments: Form schools among the spines of <i>Diadema</i> or staghorn corals, and feed on minute crustaceans in the zooplankton.  Remarkable for their strange body shape and swimming habit:  the body is encased in an armor of thin, transparent plates; they swim in synchronized groups, each fish in a vertical position with the snout pointing downwards.
