Ailaiopei

Rhinogobius nantaiensis is a goby from Taiwan, officially known only from the Tzengwen and Kaoping river basins in the south of the island. It is normally imported in mixed batches with the near-identical R. candidianus, and is the commoner of the two in the aquarium trade. It does not grow as large, has a more rounded snout, and most specimens have spot-like markings on the sides of the head.
