🐠 Sleeper Blue Dot Goby (Valenciennea sexguttata)
A Pale Cream-to-White Body With Blue-Flecked Spots Near the Gills • A Calm, Unhurried Temperament • A Functional Sand-Bed Cleaner
 
📋 The Sleeper Blue Dot Goby, also known as the Sixspot Goby, is a pale, elongated marine fish prized for its calm temperament and useful habit of sifting sand throughout the day in search of food, helping keep the substrate aerated and free of detritus.
It comes from shallow sandy lagoons and reef flats across the Indo-Pacific, named for the small cluster of blue-flecked spots near the gill area, set against a pale cream-to-white body that helps it blend into its sandy natural habitat. Every Sleeper Blue Dot Goby we ship is feeding well.
Naturally unhurried and peaceful, this species spends much of the day mouthing sand, sifting it for edible morsels before expelling it through its gills, a behaviour that makes it a functional addition to a reef tank rather than a purely decorative one. It's a notorious jumper and requires a tightly sealed aquarium. With stable water conditions and a sand bed to forage in, it thrives as a beneficial substrate-cleaning reef display fish. It reaches 12-14cm, so a 150L tank with a sand bed of at least 5cm depth suits it well.
