Care notes
An aquarium of at least 150 liters with a sandy substrate is necessary. Ideal temperature is 24-28°C, pH 8.1-8.4. This wrasse is carnivorous and enjoys frozen foods such as mysis, brine shrimp and small crustaceans. It can be kept alone or as a pair if the tank is spacious. It cohabits well with peaceful fish of similar size. Avoid dwarf shrimp and small crabs. Moderate lighting and moderate to strong flow are recommended. Weekly water changes of 10% are sufficient.
