CRUSTACEANS    293


          Stenopus hispidus
         Coral Banded Shrimp

           ORIGINS  Found on tropical reefs throughout the world’s
           oceans, particularly the Pacific.
           SIZE  Body is 2 ⁄2 in (6 cm) long.

           DIET  Meat-based foods. If frozen supplies are used, make
           sure that the food is thawed completely before use.
           WATER  Temperature 77–79°F (25–26°C); alkaline
           (pH 8.1–8.3) with SG 1.020–1.024.
         The ancestors of these shrimp were present in
         the oceans more than 10 million years ago,
         when North and South America were still
         unattached continents. As the land
         bridge formed, the populations in the
         tropical regions of the Pacific and Atlantic became
         separated, resulting in different color forms and
         new species in different locations. Female Coral
         Banded Shrimp are larger than males. They also
         have bright red banding on their upperparts, which
         appears brownish in males. Keep these shrimp in
         true pairs, if not singly, because otherwise they will
         fight to the death. Tankmates need to be chosen
         carefully because these invertebrates will prey on
         other shrimp and smaller fish. The male Coral
         Banded Shrimp is unusual in that he collects food
         for the female and actively feeds her in a cave. She
         signals by clicking her pincers, and he responds by
         passing over food.
