White-Banded Possum Wrasse Care Guide
Wetmorella albofasciata is a small, secretive Indo-Pacific reef wrasse that lives in caves and crevices, reaching about 6 cm.
Compiled by Aquairi from published sources · Published · Updated
Overview
Wetmorella albofasciata, the whitebanded sharpnose or possum wrasse, is a small reef-associated fish of the family Labridae from the Indo-Pacific. It is a secretive species reaching about 6 cm in total length, with grayish-brown to reddish-brown coloration marked by pale bands on the head.
Taxonomy
- Family: Labridae
- Genus: Wetmorella
- Scientific name: Wetmorella albofasciata
Habitat
The species is distributed across the Indo-Pacific, from East Africa to the Hawaiian and Society Islands, south to the Great Barrier Reef. It inhabits caves and crevices of lagoon and seaward reefs and drop-offs, typically at depths of at least 30 m, within a recorded range of 8-42 m.
Tank requirements
- Minimum tank volume: 80 L
- Temperature: 24-26 °C (75-79 °F)
- pH: 8.1-8.4
- Lifespan: 8-15 years
Diet
The genus Wetmorella feeds on small benthic invertebrates; in the aquarium this carnivorous wrasse is offered small meaty foods. It is reef-safe and does not harm corals.
Compatibility
This is a peaceful, reclusive wrasse that spends much time among caves and crevices. It is best housed in a mature reef aquarium with ample live rock and avoided with large, aggressive species that would outcompete it for food or intimidate it.
Breeding
Reproduction involves distinct pairing during breeding. The species is benthic to benthopelagic; captive breeding is not commonly reported.
Conservation status
According to FishBase, Wetmorella albofasciata is assessed as Least Concern on the IUCN Red List (assessed 2009).
White-Banded Possum Wrasse Breeding Guide (Wetmorella albofasciata)
Overview
The white-banded possum wrasse (Wetmorella albofasciata) is a small Labridae wrasse of the subfamily Cheilininae, described by Schultz and Marshall in 1954. It belongs to the genus Wetmorella, a group of cryptic Indo-Pacific reef wrasses, and like its congeners it is a small, secretive species associated with sheltered reef structure rather than open water.
Sexing
No external sexing key is documented for Wetmorella albofasciata in the consulted sources, and its secretive habits make wild observation rare. With no published dimorphism data for the species, reliable visual sexing cannot be described.
Spawning Behavior & Trigger
Within Wetmorella, FishBase records congeners as oviparous with distinct pairing during breeding, the general reproductive mode for the genus. For W. albofasciata specifically, the consulted sources do not document a spawning sequence, site preference or trigger, and no captive spawning has been reported.
Egg & Fry Care
No egg, larval or fry-rearing information for this species appears in the consulted sources. As a small oviparous reef labrid it is presumed to share the general wrasse reproductive pattern, but in the absence of specific data no rearing guidance can be given.
Common Challenges
Its tiny size, extreme shyness and dependence on sheltered reef crevices make the species hard to observe and condition, and the lack of documented reproductive detail leaves no basis for a captive breeding attempt. It remains a wild-collected nano-reef species in the trade.
