| Bob Fenner | Pseudocheilinus octotaenia |
Called the "Lined" Wrasses for their obvious horizontal markings, these are amongst the most desirable wrasses for peaceful all-fish marine systems and reefs. All Lined Wrasse species are Indo-Pacific or Pacific Ocean in distribution, small (about four-five inches max.), and reclusive to the point of not being seen. Don’t let any of this dissuade you from trying the genus. Outside of incidental losses from shipping trauma, these diminutive beauties can make sturdy, though shy additions. Please note that as they get used to their systems, they can develop a taste for shrimp of all sizes, including useful ones like cleaner shrimp - you've been warned. Four of the seven Pseudocheilinus described species are regularly offered in the trade. | Pseudocheilinus citrinus Randall 1999. Eastern central Pacific. To two and a half inches in length. | |
| Pseudocheilinus dispilus Randall 1999. Western Indian Ocean, Mauritius and Reunion Islands. To three inches in length. | |
Pseudocheilinus evanidus Jordan & Evermann 1903, the Pin-Striped or Striated Wrasse (2). I like this fish’s other common names, the Disappearing or Vanishing Wrasse for its bashfulness. To a grand size of three inches. Indo-Pacific, including Red Sea and Hawai'i. Two in the Red Sea. |

| Pseudocheilinus hexataenia (Bleeker 1857), the Sixline Wrasse (2). A feisty, though small (to 4") a reef tank species. Indo-Pacific, including the Red Sea in its distribution. Aquarium and Queensland, Australia images. |  
|
| Pseudocheilinus ocellatus Randall 1999. Known by several common names, take your pick: the Mystery Wrasse, the Tail Spot Wrasse, and/or the Five Bar Wrasse. West central Pacific. To four inches in length. Aquarium images. |

Pseudocheilinus octotaenia Jenkins 1901, the Eight-Lined Wrasse (2) comes in two color morphs, one more orange, the other more pinkish in body hue. Both can become agonistic toward other fishes. Under-crowding, over-decorating and keen observation are called for here, as always. Indo-Pacific, including Hawai'i.. To five and a half inches in length. Both color morphs shown in captivity. |  
|
| Pseudocheilinus tetrataenia Schultz 1960, take a guess, yes; the Fourline Wrasse (2), is mainly collected out of Hawai’i. It is also a three-incher that like all members of the genus is best kept one to a tank. Western central Pacific. To three inches total length. |
