The Knight Goby is a beautifully-marked adaptable species that is not often seen in the hobby!

This Goby does well in both hard, alkaline freshwater and slightly brackish (1.005sg). We keep this goby in alkaline freshwater.

The Knight Goby (Stigmatogobius sadanundio), is a rare goby that is native to many countries including Pakistan, India, Thailand, and Malaysia. It is known for its unique grey body with black dotting as well as its distinctive extended dorsal fin. Both males and females are beautiful specimens, but males tend to get a more extended dorsal fin. Females also stay a bit smaller and develop a more round body. This fascinating, semi-aggressive fish is a carnivorous goby that inhabits estuarine zones, but is more commonly found in freshwater.

 

An aquarium with moderate water flow and very clean, clear water is required for the Knight 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 achieved with airstones instead of powerheads if so desired.

 

The Knight 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 should be fed live and frozen foods as well. As long as it is kept in a well-maintained, mature aquarium, the Knight 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.

 

Most fish large enough to not be considered prey will make great additions to a Knight Goby tank. Tankmates with long, flowing fins should be avoided as they may get nipped. 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 Knight Goby is not outcompeted for food.

 

There has been reproduction of the Knight Goby in the hobby, but the number of reported cases is limited. 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.
