The Barcheek Goby is an outgoing species that has incredible potential for stunning multi-coloration as it matures!
The Barcheek Goby (Rhinogobius giurinus), is a rare freshwater goby that is native to Taiwan, Japan, China, and Korea. It is known for the brilliant multi-coloration that it develops as it matures as well as the lined facial markings that are its namesake. Both males and females are colorful, but males also often develop extended dorsal and anal fin rays. This fascinating, generally peaceful fish is a carnivorous goby that inhabits rivers and streams of very high oxygen content. Unlike many other Rhinogobius species, some populations of the Barcheek Goby are amphidromous, meaning that their fry undergo a pelagic stage where they live in marine water before returning to freshwater. However, some populations of this species live their entire life cycles in freshwater habitats.
An aquarium with moderate water flow and very clean, clear water is required for the Barcheek Goby. This fish is typically native to shallow, clear streams and pools and it is sensitive to declines in water quality, so regular aquarium maintenance is a must. It does not require the extremely high water flow that Stiphodon gobies and hillstream loaches require, so its high oxygen needs can be acheived with airstones instead of powerheads if so desired.
The Barcheek Goby feeds mostly on very small invertebrates in nature. In the aquarium, it is known to readily accept frozen meaty foods such as bloodworms, Mysis, Daphnia and Artemia. This fish will sometimes also accept high-quality dry foods, but it still shoud be fed live and frozen foods as well. As long as it is kept in a well-maintained, mature aquarium, the Barcheek Goby is a hardy and entertaining fish. It will not bother aquarium plants. In fact, Anubias species are an excellent plant to keep with this goby.
The Barcheek Goby is a subtropical fish that should not be extensively kept at a temperature above 75° F (24° C), although it does experience much higher temperatures in some warmer seasons in its native areas. Many batbs, tetras, hillstream loaches, and other peaceful, durable fish are good tankmates for the Barcheek Goby. Dwarf shrimp are likely to be eaten by this fish, but some invertebrates that are large enough not to be eaten or bullied can make good tankmates as well. The Barcheek Goby is a bit larger and more pugnacious (including with its own kind) than some other members of its genus, so it may not cohabitate well with other bottom-dwelling species.
There are reported cases of the Barcheek Goby spawning in the aquarium, so successfully raising this species in the home aquarium is possible.
