The red-spotted goby, Rhinogobius rubromaculatus, is endemic to Taiwan and apparently quite common in central and western parts of the island. Fish from the Linbian river in the south are smaller, with larger and more intense red spots, and have been called R. rubromaculatus 'rot' or 'red' in the hobby, but they show only minor genetic differences. Among the less problematic members of the genus to breed, it can spawn year-round in aquaria.
