      Thalassoma purpureum
      Max. size: 46.0 cm TL (male/unsexed); max. published weight: 1,210 g
      Environment: reef-associated; marine ; depth range 0 - 10 m
      Distribution:
      Gazetteer Indo-Pacific: Red Sea and East Africa to the Hawaiian, Marquesan, and Easter islands, north to southern Japan; south to Lord Howe, Kermadec, and Rapa islands; throughout Micronesia. Southeast Atlantic: southeast coast of South Africa. Replaced by Thalassoma virens in the Revillagigedo Islands.
      Morphology: Dorsal spines (total): 8; Dorsal soft rays (total): 12-14; Anal spines: 3; Anal soft rays: 10-12. T. purpureum and T. trilobatum have nearly identical initial phases . They differ slightly in details of the head markings, and T. purpureum has a slightly longer head, shorter pectoral fins, and attains a larger size. Females best distinguished by the 'V' mark on the snout. Initial phase with a vertical dark red line below front of eye usually with a branch to front of snout.
      Biology: Found almost exclusively in the surge zone of outer reef flats, reef margins, and rocky coastlines, down to a depth of about 10 m. Occurs in groups of females that are spread out over large reef sections and dominated by few males. Males grow much larger than females. Feeds on small invertebrates (crabs, sea urchins, brittlestars, mollusks), small fishes, echinoids, ophiuroids and polychaetes
      Aquarium Care:Has a temperature range of 75 - 83°F (24 - 28°C) and has a natural diet of benthic invertebrate and small fishes. Requires a meaty diet consisting of finely chopped enriched fish or shrimp flesh, mysis, and enriched brine shrimp with two to three feedings per day. Sometimes bury themselves if frightened. Usually, they sleep under rock shelves, on or under a coral branch, in a crevice, or directly on the sand surface, however, providing a deep sandbed of about 5 inches (12.5 cm) of fine-grained sand would be a good idea. They are highly active swimmers and need plenty of swimming space. They will also eat snails, worms, sea stars, urchins, and clams.
