What to know before you buy.
The Knight Goby is a bottom-dwelling fish with a pale body covered in striking dark spots. It is territorial towards its own kind and other bottom-dwellers, so it's best kept singly or in a large tank with plenty of hiding spots to break lines of sight. While it can adapt to freshwater, it thrives in low-end brackish conditions.
