Male Pelvicachromis pulcher kribensis cichlid Aquarium fish

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