Gobiodon citrinus
Gobiodon citrinus reaches up to 6 cm. Its body is elongated, laterally compressed, with a uniform bright yellow coloration sometimes marked by fine blue lines on the head. It has large pectoral fins and a rounded caudal fin. It secretes a toxic mucus that protects it from predators. Sexual dimorphism is subtle, with males slightly larger during breeding season.

Care
Care notes
A minimum 40-liter tank is recommended, with moderate lighting and good water flow. Stable parameters: temperature 24-28°C, salinity 1.020-1.025, pH 8.1-8.4. It is essential to provide Acropora corals or branch-like structures for resting and security. Diet: small frozen crustaceans (brine shrimp, mysis) and enriched flake food. Compatible with most peaceful fish and reef invertebrates. Caution: do not keep with aggressive fish or predatory crabs.
