Gobiodon acicularis

Gobiodon acicularis – Black Coral Goby for Reefs

Gobiodon acicularis, known as the black coral goby, is a small reef fish with a completely black fusiform body, often seen perched among coral branches or discreetly gliding at the bottom of the tank. It is an elegant, discreet, and useful species.

A structural fish for branching corals

This goby lives in passive symbiosis with branching hard corals (such as Acropora) or branching soft corals. It finds refuge and stability there, observing its environment from cavities or crevices. It does not harm well-established corals and helps create a natural and functional ambiance in the tank.

A discreet fish, sometimes useful against algae

Some Gobiodon acicularis individuals may pick at algae or biofilms present on corals and live rocks, thus contributing to the natural management of microflora. This behavior is not systematic but can be beneficial in a well-balanced tank.

Maintenance conditions

• Recommended minimum volume: 80 liters
• Temperature: 24°C to 27°C
• pH: 8.0 to 8.4
• Decor: branching hard or soft corals
• Behavior: territorial, calm, sedentary

Diet

• Microfauna, biofilm, and small algae
• Pellets or powders for small omnivores
• Artemia nauplii or plankton as a supplement

Although it may pick at surfaces, a varied and regular diet is essential, especially in a young tank or one with little colonized microfauna.
