Ribboned Sweetlips Plectorhinchus polytaenia occurs in the tropical Indo-West Pacific from West Coast India to Australia in a depth range from 5-40m on coastal and seaward reefs, max. length 50cm. The species is found singly, in small groups under ledges or large resting aggregations by day, foraging for small invertebrates at night. Adults are found on deep, current-prone slopes with rich invertebrate growth; juveniles on sheltered reefs nearby. \nBluestreak Cleaner Wrasses Labroides dimidiatus usually occur in pairs in the tropical Indo-Pacific in a depth range from 1-40m, usually 1-30m, max. length 14cm. The species creates 'cleaning stations' to which fishes come to have crustacean ectoparasites and mucus removed. Cleaning intensity is not related to client size or commonness. Even hands of divers will be cleaned if presented to the cleaning station! \nThis specimen was encountered in the Triton Bay, Kaimana Regency, West Papua Province, Indonesia, 3°54'50.604 S 134°6'0.828 E at 15m depth.

Mandarin fishes inhabit shallow protected lagoons and inshore reefs. They occur in the Western Pacific from Ryukyu Islands to Australia, usually in small groups spread over small area in a depth range from 1-18m, max. length 7cm. \nMandarinfish do not have scales, but a mucus layer for protection. It is not only a stinky slime they produce, but they also secrete a toxin to protect them against predators. Their dramatic colouration, known as aposematism, is a warning: unpalatability and toxicity - both prey and predator get to live longer. \nThe couples perform an extraordinary courtship dance at dusk. Females gather at the reef, judging if a male is worthy. A male who has successfully courted a lady attaches to her at the pelvic fin. Then the pair swim up from the reef towards the waters surface, releasing a cloud of sperm and around 200 eggs smaller than 1mm. \nThis specimen is a male: The presence of an elongated spine at the front of the first dorsal fin of males is distinctive. Females will not have this spike and will have a rounded first dorsal fin instead. In this case, there was a female too, but she didn't make it into the photo.\nBanda Neira Island, Indonesia, \n4°30'40.842 S 129°53'19.71 E at 1.5m depth
