With just a few clicks of a mouse, you can purchase your very own redtail garra, a type of fish that feeds on algae. Information about the fish’s biology, however, is much less easily obtained. That’s because redtail garra, although popular in the aquarium trade since the early 2000s, has until now been unknown to science.
Researchers were peripherally aware of the fish’s existence, but “discovering” a new species requires scientific description based on specimens collected in their natural environment. Redtail garras appear to be restricted to a small stretch of river straddling the border between Thailand and Myanmar. The locality is isolated and difficult to reach, so wild redtail garras have existed in relative obscurity, despite their global appeal.
Larry Page, curator of ichthyology at the Florida Museum of Natural History, has surveyed fishes in Thailand every year since 2007….
