In Indonesia and the Philippines, we find a very different beast, which has a rather truncated caudal fin bordered posteriorly in blue, rather than the yellow seen in the Indian Ocean. The pectoral fins have just the single, apical spot, and the dorsal fin often has a yellowish marking anteriorly along the base, as well as a darkened posterior tip. The correct name for this fish should be Pseudanthias cheirospilos (Bleeker 1857), and you will occasionally see it used in aquarium references; however, scientific publications ignore this nomenclature entirely.

Japan is home to its own unique flavor, which you will occasionally see recognized as a distinct species, Pseudanthias nobilis (Franz 1910). It is easily told apart by the bright white dorsal fin of nuptial males, the darkened posterior markings found at the tip of the dorsal, anal and caudal fins and the relative profusion of yellow along the scales of the body. It occurs throughout the main islands of Japan, as well as the Ryukyu Arc, where it likely intermixes with P. cheirospilos. Aquarium specimens are a rarity, unlike the other fishes discussed here.

Finally, the reefs of Melanesia and Australia are home to their own unique species. This fish has a bright yellow anal fin in males, and it tends to have a brighter and more consistent yellow patch in the dorsal fin. In other respects, it is quite like those found elsewhere in the Pacific, though it does appear somewhat more purple in color relative to the dull-mauve of P. cheirospilos, the yellow-orange scalation of P. nobilis, and the bicolored appearance of the true P. squamipinnis in the Indian Ocean. Personally, I find this to be the most attractive member of the group.We have relatively little data on this fish, with specimens from Fiji and Tonga being the best documented. It’s possible that the genetic difference supported in the phylogenetic tree shown here is only relevant to the distinct ecoregion of Fiji+Tonga+Samoa, with those found elsewhere (Australia, Vanuatu, Solomon Islands, Papua New Guinea) representing one or more additional distinct populations. However, phenotypically, they all look essentially the same; more study is needed. There is no name that can be applied to this fish, so, at some point, when it’s population structure has been full elucidated, it will need to be scientifically described.
