Redbreasted Wrasse Cheilinus fasciatus occurs in the tropical Indo-Pacific from the east coast of Africa and islands of the western Indian Ocean to Micronesia and Samoa and Tonga, north to the Ryukyu Islands, Japan and south to Queensland, Australia in a depth range from 4-60m, but usually not deeper than 40m, max. length 40cm. This specimen was encountered at the Iro Wreck, a 143 meter oil tanker wreck since March 1944, WWII, was ordered by the Japanese Navy during the 1920´s building programs. Although heavily overgrown with black coral and sponges, the torpedo hole is still clearly visible. The wreck sits upright between 15m and 36m of water. The outside of the ship has developed a nice coating of colourful invertebrates, mostly sponges and oysters. Palau 7°17'40.08 N 134°25'15.51 E at 20m 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
