purple fairy wrasse
In this brilliantly colored wrasse, the ground color ranges from blue to teal to turquoise, depending on available lighting. Cirrhilabrus solorensis is extremely ubiquitous in the aquarium trade and is of little monetary value. In C. cf. While some of the hybrids are easily diagnosed, a few are iffy and highly subjective. Females of C. luteovittatus are of the usual form, being relatively drab and unmarked with a series of fine spotting along the dorsum. aurantidorsalis, which will be elaborated upon in the individual species discussion. Although it would seem logical to classify C. luteovittatus and C. randalli as sisters in the phylogenetic tree, the biogeography between the two species does not fully support that conjecture. Could this be a regional form of Cirrhilabrus cf. This video is unavailable. Ventrally, this species is unmarked and uniformly white (or sometimes a light yellow), with the lower head always being a pristine and blemish-free white. Froese, Rainer and Pauly, Daniel, eds. Cirrhilabrus aurantidorsalis possibly hybridizes with C. cf. It can be found in the aquarium trade.. The ryukyuensis form of C. cyanopleura never develops such extensive elongation of its yellow flank, and this could possibly point to the occurrence of C. randalli in Indonesia. The male of C. cf. The living coloration of C. solorensis was unknown to many then but eventually revealed itself through the passing of time. Quick View. The lightening of the indigo scales and the faint emergence of an underlying orange along the dorsum in the specimen of C. solorensis above seems to suggest some genetic input from C. aurantidorsalis. Like C. cyanopleura, displaying males tend to puff up their gular flap, which may be edged in blue during this event. The possible extension of this species into the Komodo region is discussed at the end of this article. Etymology. This means that a whole spectrum of transitioning colors can present themselves during the development of the species throughout its various life stages, further blurring the lines of identification. Blue Sided Fairy Wrasse (Cirrhilabrus cyanopleura) Starting at: $ 55.99. However, whether or not the ryukyuensis form is indeed a diverging taxon capable of maintaining genetic distinction, or whether it will eventually hybridize back into a single homogenous taxon remains unknown for now. The head is fuchsia to magenta, and the body is blue to purple. The flat, monotonous and open habitat is often colonized by low-lying soft coral such as Xenia and Sinularia, in which the females and males frequently cavort around. Froese, Rainer and Pauly, Daniel, eds. It doesn’t appear to have any significant nuptial pattern, and displays in the same way C. cyanopleura does. The caudal fin is a rough rhombus, becoming increasingly spade like in terminal males. The yellow equatorial streak in both species could be regarded as a shared trait, once widespread across the Pacific but subsequently lost in the evolution of the other group members. Cirrhilabrus aurantidorsalis could be speciating right now due to its geographical isolation, or the two population might have already been speciated, but recently reconnected in their ranges. This appears to be the terminal male form of this “species”. Should the very unlikely, but not impossible, chance that C. randalli waifs to Indonesia, would it be able to hybridize with its other clade members out of desperation to find a mate? Cirrhilabrus cf. Mixing fairy wrasses can be done but is best attempted in a larger aquarium. We’re proposing in this article the usage of “Banda Fairy Wrasse” as the colloquial name, as it reflects this variant’s distribution with respect to the other clade members. The females are a dusky greenish-grey and adorned all over with the chainmail like markings of this group. The scales along the dorsum are thickly edged in the same indigo as the operculum, and these scales can be so copiously colored that they form a thick indigo band instead of the usual chainmail markings. This characteristic made a brief cameo in Cirrhilabrus scottorum and C. melanomarginatus of the scottorum group, and foreshadowed a cladistic relationship between the two. This habitat’s flora and fauna is quite niche and specific to the Micronesian and Marshall Island chains, and is shared with a few other sympatric species such as Cirrhilabrus johnsoni and C. rhomboidalis. The solorensis clade females are more uniformy colored, without a clear “hood” seen in C. cyanopleura, instead having a burgundy-red head. The cyanopleura group is by far the most challenging, taxing and mind-numbing of the Cirrhilabrus groups so far, and this is only the beginning. It is possible that Cirrhilabrus solorensis is able to form hybrids with Cirrhilabrus aurantidorsalis in Sulawesi, and in at least one photographic documentation, this seems to be highly plausible. This is a very unique characteristic restricted to members of this group, with the exception of the unrelated C. rubrisquamis. solorensis, but the maraschino cherry hood in this form never extends pass the pectoral fin base. Allen and Erdmann lists the maximum size for the group members at 10-11 cm, but aquarium housed specimens have the potential to get much larger, up to 15cm. This appears to be highly similar to the Balinese red headed Cirrhilabrus cf. While the expression of solorensis traits are not extremely apparent, it does manifest itself nicely in the heavily shaded operculum. solorensis from Bali, as well as the females of the other Indonesian clade members. In a study published by Gerlach et al, it was concluded that males of Cirrhilabrus solorensis emit red fluorescence at 650-700nm during displays of courtship and aggression. The intensity and extensiveness of the orange backs, of course, are more pronounced in matured and terminal males. Save 17%. Information regarding the relationships between the known species is scant to say the least. The extensive hooded marking on the posterior dorsum seems to suggest this. This species can reach a total length of 12 cm (4.7 in). Like Cirrhilabrus cyanopleura, its gaudy, almost fake and plastic-like coloration makes it a very popular choice for novice aquarists. A plausible cause for this could be attributed to the yellow-orange dorsal mark being greatly exaggerated downwards. The ventral portion is a lighter, mangosteen purple to white. Although C. cyanopleura and C. solorensis were some of the earliest known Cirrhilabrus, not much is known about their biology and phylogenetic proximity to the other species. aurantidorsalis instead. Juveniles are mostly maroon to greenish with a single peduncular spot and a white tipped snout – an appearance shared by many other species in various groups and is therefore of limited use as a diagnostic feature. The area behind the pectoral fin is sometimes, but not always, slightly tinted in violet, and the scaling just adjacent to this is always thickly edged in claret. Cirrhilabrus cf. The species appeals greatly to the novice aquarist, ticking all the right boxes for affordability, hardiness and visual appeal. Cirrhilabrus solorensis is not known to display any visible nuptial coloration, but, as mentioned in the group discussion previously, the males are able to emit red fluorescence in their excited state around the operculum and dorsum region. At the northern limit in Lembeh, C. cf. However, with close scrutiny, the two can be rather confidently separated based on a few key characteristics. A fairly common aberration involves C. luteovittatus developing a highly xanthic dorsum, which in extreme cases can totally obliterate the underlying burgundy ground color and merge with the existing yellow stripe. We managed to chance upon some of these hybrids cavorting with various other species. The caudal fin is strongly rhomboidal in terminal males. Both forms are exceedingly common in the aquarium trade and are of little value, being rather cheap and affordable. This would suggest genetic involvement with one of the striped species of the solorensis clade, and with C. randalli confined to the far-flung region of Northwestern Australia, Cirrhilabrus luteovittatus from Micronesia seems more likely. 2: Aquascaping the Rock Wall, The Best Lids for Saltwater Aquariums – Reef Builders Gear Guide, Threatened Controller Manufacturer Attempting to Shut Out New Lower Cost Competitor. It becomes progressively less common further south in Indonesia. Quick View. Halichoeres bivittatus. The specimen above is 10cm in length, far larger than the usual size at which this phenotype is often photographed. Both forms of this species are capable of forming hybrids with Cirrhilabrus solorensis, and possibly Cirrhilabrus luteovittatus, which will be discussed in detail later in this article. It appears that color change during nuptial display is limited and reduced to only the lightening of the dorsal fin, with no change in overall body coloration, nor is there a presence of metallic iridescence or lightening of the body as seen in all other fairy wrasses. The specific epithet luteovittatus translates to “yellow-stripe”, and this is very clearly displayed in the males. This species is capable of forming hybrids with Cirrhilabrus cyanopleura and possibly with Cirrhilabrus aurantidorsalis. Although this species has not been documented outside of its range, a few curious specimens that appear to be hybrids with traits of C. randalli have been documented in the Indonesian archipelago.
