Their bright bluish-purple colors and constant activity make Sixline Wrasses a stunning addition to any marine aquarium. They are active during the day, swimming in and out of caves and grottos created with live rock and sleeping in a mucus cocoon at night to avoid detection by predators. Sixlines are one of the smaller wrasse species, are reef safe and are usually well-behaved around other fish. Some hobbyists report Sixlines being aggressive toward newly added fish, so it’s suggested that they be one of the last fish introduced to your aquarium. They are carnivores and are often used to eradicate bristleworms, pyramid snails and flatworms. They have also been observed “cleaning” ecto-parasites from the bodies of tank mates. They will eagerly devour copepods as well, so it’s best to avoid keeping them with Mandarins or other finnicky eaters. (Mandarins are not recommended for beginners or newly set up aquariums.) Sixline Wrasses accept a wide range of meat-based flake, pellet and frozen foods.
