         SQUIRRELFISH




         The red color, large eyes, and fitful
         movements of these attractive fish are
         reminiscent of terrestrial squirrels. The eye
         size is an adaptation for nocturnal living in
         sheltered areas near the base of coral reefs,
         where it is vital to gather as much light as
         possible from the gloomy surroundings.
         Certain species are known as soldierfish,
         and this name is often used interchangeably
         with squirrelfish, but in zoological terms,
         only the subfamily Myripristinae can be
         correctly described as soldierfish.

         Squirrelfish spend the daylight hours sheltering in crevices
         then emerge at night to patrol their territory. This is a group
         of Bigeye Soldierfish (Myripristis bernelti).

         features of this species. It will adapt to daylight              where they are emphasized by their silvery
         feeding. Soldierfish are fairly easy to keep, but                 outlines. These squirrelfish are shy by nature,

                                         soldierfish, it can vocalize, making a grunting sound
                                         by contracting the muscles surrounding its swim
                                         bladder and grinding its pharyngeal teeth (located
                                         at the back of the throat). Grunting is most likely to
                                         be heard if the fish feels threatened. This species
                                         usually swims in the lower part of the aquarium,
                                         although, like other soldierfish, it prefers to feed in
                                         the upper levels, rather than from the substrate.
