Paddlefin Wrasse Marine Fish

$90.60

The Paddlefin Wrasse, also known as the Cortez Rainbow Wrasse, features bold rainbow coloration that changes across distinct life phases. Native to Central America and the Sea of Cortez, juveniles and initial phase females display vibrant striped rainbow patterning, while terminal phase males develop striking adult coloration.

This active saltwater species thrives in an established aquarium of at least 283.9 liters with plenty of rockwork for hiding. Due to its semi-aggressive and territorial nature, it is best kept with larger tank mates and introduced as the final addition to the community.
