The Eight Line Flasher Wrasse, Paracheilinus octotaenia,\ Like other species, juveniles and adults feature vastly different coloration patterns and body types. The juvenile Eight Line Flasher Wrasse is a pink/blue color with colored horizontal lines across its body. Juveniles also feature elaborate striping around the eyes creating a beautiful mask. As they mature into adults, the Eight Line Flasher Wrasse keeps its characteristic eight blue horizontal lines but changes to a more orange/red body. Its dorsal, anal, and caudal fins flare out and the beautiful mask is mostly retained.
The Eight Line Flasher Wrasse \requires a tank with plenty of free swimming space, a sandy substrate, and a tightly sealed lid to prevent escapes.
