Care notes

A tank of at least 30 liters is sufficient, but a larger volume is recommended for stability. Maintain temperature 24-28°C, pH 8.1-8.4, and salinity 1.020-1.025. Decorate with live Acropora corals or structures mimicking their branches. This goby is carnivorous: accepts small frozen crustaceans (brine shrimp, mysis) and fine pellets. It is peaceful with most fish but may become territorial towards other yellow gobies. Beware of jumping: cover the aquarium.
