Keep the water temperature between 72-78°F (22-26°C), pH at 8.1-8.4, and salinity at 1.020-1.025 specific gravity.
Include live rock and other structures to offer hiding places and grazing opportunities.
Offer a varied diet of meaty foods like frozen mysis shrimp and brine shrimp, along with high-quality marine flakes and pellets.
Keep the Radiant Wrasse with other peaceful species and avoid housing multiple males to prevent territorial disputes.
Radiant Wrasses can grow up to 4.5 inches (11.5 cm) in length.
Maintain a temperature of 72-78°F (22-26°C), pH between 8.1 and 8.4, and salinity at 1.020-1.025 specific gravity.
