Care
The Royal Pencil Wrasse is known from open areas that are covered with rocks, rubble, and coral patches, at depths from 12-40m (39-131ft). It is usually observed in small harems, comprised of one male and several females, browsing the substrate for molluscs and foraminiferans. This elongate wrasse is one of 11 currently known species of Pseudojuloides, and although all are incredibly beautiful, this genus is considered rather delicate and does have some specialist care requirements that must be fulfilled by the advanced aquarist if these fish are to acclimatise well to life in captivity. The Royal Pencil Wrasse requires a very mature, spacious aquarium with plenty of healthy live rock and sand that supports its natural diet on an ongoing basis, if it is to thrive. If added to a newly set up tank, it will starve to death. There should be plenty of hiding places amongst the rockwork, with enough depth of substrate (7.5cm/3" of fine sand) for the fish to bury if it feels threatened. Because of the difficulties in feeding this wrasse, it should not be kept with fish that require a similar food source to survive, as otherwise one species may out-compete the other. There should be relatively calm areas in the tank that allow it to locate food successfully. Tankmates should be peaceful and of an easygoing nature so that the Royal Pencil Wrasse does not feel harassed and subsequently stops venturing out to feed. Keep only one male per tank; groups, comprised of one male and several females, can sometimes be kept together successfully (added simultaneously) but larger numbers should only ever be considered for exceptionally voluminous aquaria, as in the average sized aquarium, natural prey will deplete too quickly with that many fish requiring the same diet. Do not house with different Pseudojuloides species, other wrasses, or pugnacious dottybacks and hawkfishes, as they will fight for territory. When choosing your Royal Pencil Wrasse, check that its body is not emaciated, and that it is actively searching for food. It is not uncommon for a newly added pencil wrasse to hide beneath the substrate whilst it adjusts to its new surroundings and altered circadian rhythm; in such cases it is best to leave them be, they will usually begin to explore within a couple of days. These fish require stable and optimal water conditions at all times, so a good filtration and maintenance regime is a must. Ensure that the aquarium has tight fitting coverslides with no small gaps in the hood, as these fish are expert jumpers. May also be seen on sale as Pink Pencil Wrasse (a name that really only suits the pinkish-orange females) or Severns' Wrasse. Not recommended for beginners.
Feeding
Very challenging to feed. This species will spend many hours searching out micro-invertebrates living in amongst the live rock and substrate. It must be provided with natural prey. A constant supply of tiny live foods for this purpose can be cultured in a fishless refugium. Will often take vitamin-enriched brineshrimp, and sometimes Mysis, but this alone will not provide enough sustenance.
Breeding
This species has not been bred in the home aquarium.
