What is its maximum size?
Up to approximately 14–15 cm in length.
Where is its origin and where is it exported from?
The Chalk Goby originates from the Indo-Pacific, including areas around Indonesia, the Philippines, Australia and the western Pacific islands. It is commonly exported for the aquarium trade from countries such as Indonesia and the Philippines.
Is it reef compatible?
Yes, with caution. It is generally safe with corals and most invertebrates. However, it sifts sand for food and may cover corals or live rock with sand while digging and maintaining its burrow.
What should I feed it?
Feed a varied diet of small meaty foods, including frozen mysis shrimp, enriched brine shrimp, finely chopped seafood and suitable sinking marine pellets. It naturally sifts sand to find tiny organisms, so ensure it receives enough food. It may struggle to survive in aquariums with insufficient natural food in the substrate.
How many can I keep?
Best kept singly or as an established pair. Two compatible individuals may share a burrow, but avoid keeping multiple individuals together in a small aquarium, as territorial disputes can occur.
How compatible is it with other fish?
Generally peaceful and suitable for community marine aquariums. It does well with other peaceful fish but may be intimidated by aggressive or highly territorial tankmates. A deep, fine-grained sand bed is essential for burrowing, and a tight-fitting lid is recommended because gobies can jump.
