Knight Goby

A soft, sandy substrate is ideal for this species. Also provide lots of caves, nooks and crannies where it can lurk and form territories. Although commonly found in freshwater in nature, this goby appears to do better with the addition of salt in the aquarium. Saying that though, this species has also been kept with great success in hard, alkaline freshwater. It will be more active and visible during daylight hours if you provide dim lighting.

Don’t try to keep it with much smaller species as it will eat anything it can fit in its mouth. It may also nip the fins of slow-moving or long-finned species.
