About Koumansetta rainfordi Whitley, 1940
Koumansetta rainfordi, commonly called the old glory or Court Jester goby, is a species of goby. It is native to tropical reefs of the western Pacific Ocean, where it lives at depths ranging from 2 to 30 metres (6.6 to 98.4 ft). This species grows to a maximum length of 8.5 centimetres (3.3 in) measured along its standard length. It is also available in the aquarium trade. Its specific name honors E. H.
