(Valenciennea strigata)
What is its maximum size?
The Blue-cheek Goby can grow to approximately 18 cm (7 inches) in length. It is an active, bottom-dwelling sand-sifting species that requires plenty of open substrate for feeding and burrowing. A spacious aquarium with a mature sand bed is essential for its long-term health.
Where is its origin and where is it exported from?
The Blue-cheek Goby originates from the tropical Indo-Pacific region, with a distribution extending from the Red Sea and East Africa across the Indian Ocean to Southeast Asia, northern Australia and the central Pacific. It is commonly found around coral reefs, lagoons and sandy reef slopes. Specimens entering the aquarium trade may be exported from countries such as Indonesia, the Philippines and Sri Lanka, depending on collection and supply sources.
Is it reef compatible?
Yes, the Blue-cheek Goby is generally considered reef safe. It does not normally damage corals or deliberately prey on ornamental corals. However, it constantly sifts sand through its mouth and gills while searching for food, which can cover low-lying corals and disturb unsecured frags. Its burrowing activity may also undermine rockwork if rocks are not firmly secured.
What should I feed it?
The Blue-cheek Goby feeds by sifting sand for small worms, crustaceans and other microscopic organisms. In captivity, offer a varied diet including enriched mysis shrimp, enriched brine shrimp, finely chopped seafood and suitable sinking marine pellets.
Although it naturally feeds from the substrate, it should not be expected to survive solely on the organisms in the sand bed. Target feeding near its preferred feeding area may be necessary, particularly in newer aquariums. Feed small portions once or twice daily and monitor its body condition closely to ensure it is receiving enough nutrition.
How many can I keep?
The Blue-cheek Goby is best kept singly or as an established, compatible pair. Pairs may share a burrow, but individuals can become territorial towards other sand-sifting gobies. Keeping multiple specimens requires a larger aquarium with plenty of substrate and separate territories. Avoid adding several individuals together without sufficient space.
How compatible is it with other fish?
The Blue-cheek Goby is generally peaceful and suitable for many community marine and reef aquariums. Compatible tank mates may include clownfish, tangs, peaceful wrasses, cardinalfish and other non-aggressive reef fish.
Avoid aggressive fish that may intimidate it or prevent it from feeding. It may compete with other sand-sifting gobies for food and territory. A secure lid is recommended, as this species can jump when startled.
