The Candi River Goby is a beautifully-marked riverine species that is not often seen in the hobby!
The Candi River Goby (Rhinogobius candidianus), is a rare freshwater goby that is native to Taiwan. It is known for its unique red, blue, yellow, and orange markings as well as its distinctive facial features. Both males and females are colorful, but males have an elongated first dorsal ray and a longer jaw. This fascinating, generally peaceful fish is a carnivorous goby that inhabits rivers and streams of very high oxygen content.
An aquarium with moderate water flow and very clean, clear water is required for the Candi River Goby. This fish is 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 Candi River 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 Candi River 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 Candi River 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 Taiwan. Most small rasboras, tetras, hillstream loaches, and other small, peaceful fish are good tankmates for the Candi River Goby. Dwarf shrimp are likely to be eaten by this fish, but any peaceful invertebrates that are large enough not to be eaten can make good tankmates as well. Peaceful bottom-dwelling fish are also a possibility, but care must be taken to make sure that the Candi River Goby is not outcompeted for food.
There are reported cases of the Candi River Goby spawning in the aquarium. This fish does not go through the same saltwater larval stages that many other freshwater gobies experience, so successfully raising this species in the home aquarium is possible.
