白骑士虾虎
Stigmatogobius sadanundio, or the Knight Goby, is a member of the family Gobiidae of the order Perciformes. Of the true gobis, Stigmatogobius sadanundio is a very popular.
Knight Gobies live in fresh and brackish waters in Borneo, Java, Sumatra, and the Philippines. Knight Gobies are territorial bottom-dwellers, but usually won't bother mid and top level fishes[
There are two dorsal fins on this gray-blue fish: the first consists of about six stiffly held rays (often with a black blotch); the second is equal in length to the long-based anal fin. Both carry dark spots.
The Knight Goby should be kept singly with other mid-level species. When placed in an aquarium with fish of the same species quarels may arise as this is a very territorial fish. It does best in low light, as bright light makes it skittish. It needs plenty of rocks, caves, and natural territorial boundaries. Good tankmates are swordtails and sailfin mollies.
