The Paddlefin Wrasse, also known as the Rainbow or Cortez Rainbow Wrasse, undergoes a remarkable transformation as it matures. Juveniles exhibit predominantly black coloration with a yellow and pink belly. However, as they grow into adults, their appearance brightens into a stunning array of colors. The body takes on a reddish hue, while the head area and fins transition to beautiful shades of blue and green. Adding to the allure of the adult fish is a vibrant yellow band located just behind the head. These wrasses are relatively smaller compared to other species within the genus, making them an excellent addition to a saltwater fish-only aquarium.

To provide a suitable habitat for the Paddlefin Wrasse, a tank of at least 75 gallons is recommended, along with larger and more aggressive tank mates. Ample rockwork should be available for hiding spots. As they become territorial, introducing them as the last fish in the community is advisable to avoid aggression towards new additions. If the tank is 125 gallons or larger, they may be kept with a mate. It's worth noting that the Paddlefin Wrasse may consume crustaceans, mantis shrimp, and bristleworms, but it does not harm corals or live plants.

To maintain the health and vibrancy of the Paddlefin Wrasse, a well-balanced diet is essential. Provide them with vitamin-enriched frozen mysis shrimp, frozen brine shrimp, and other meaty foods. Additionally, offering high-quality marine flake and marine pellet food can help complement their dietary needs.

By providing the appropriate environment and a nutritious diet, you can admire the splendid colors and captivating behavior of the Paddlefin Wrasse in your saltwater fish-only aquarium.
