Sixspot Sleeper Goby
The Sixspot Sleeper Goby (Valenciennea sexguttata), also known as the Sleeper Blue Dot Goby, is an attractive and highly active sand-sifting goby recognised by its pale body and distinctive bright blue spots around the face.
A brilliant addition to established marine aquariums, this species spends much of its day taking mouthfuls of sand, filtering out small organisms and edible material before releasing the clean sand back onto the substrate. This natural behaviour makes the Sixspot Sleeper Goby fascinating to watch while also helping keep the sandbed turned over.

The Sixspot Sleeper Goby is a lively and engaging addition to my tank. It constantly sifts through the sand, which keeps the substrate active and clean. The bright blue spots stand out well against the pale body. It’s easy to care for and fits well in a mature marine setup.

I’ve had this goby for three months now and it’s very active. It enjoys the sand-sifting behavior and brings a lot of visual interest. The water parameters are stable, and it seems to be thriving in the current conditions.

This goby is a real highlight in my aquarium. The blue spots are striking and the fish is always moving around, helping to keep the sandbed from settling. It’s peaceful and doesn’t show signs of aggression.
