Halichoeres melanotis Care Guide
Halichoeres melanotis is an eastern Pacific reef wrasse from Mexico to Costa Rica that feeds on small reef organisms and buries in sand.
Compiled by Aquairi from published sources · Published · Updated
Overview
Halichoeres melanotis is a marine wrasse of the family Labridae from the eastern central Pacific. Like its congeners it is a reef-associated benthic feeder that buries in sand when threatened or at night.
Taxonomy
- Family: Labridae
- Genus: Halichoeres
- Scientific name: Halichoeres melanotis
Habitat
FishBase records the species from the eastern central Pacific, from Mexico to Costa Rica, including Cocos Island. It is found on reefs at a depth range of about 8 to 37 m in tropical waters.
Tank requirements
- Minimum tank volume: 200 L
- Temperature: 24-26 °C (75-79 °F)
- pH: 8.1-8.4
- dKH: 8-12
- Specific gravity: 1.024-1.026
- Maximum size: about 13 cm total length (FishBase)
- Lifespan: 5-10 years
A sandy substrate deep enough for burrowing suits this species, in line with other Halichoeres.
Diet
Halichoeres melanotis is a carnivore with a trophic level around 3.5, taking small reef invertebrates. Aquarium specimens accept meaty frozen and prepared marine foods in several small feedings per day.
Compatibility
It is a peaceful, bottom-oriented wrasse compatible with calm reef tankmates such as tangs, clownfish, cardinalfish and anthias. Aggressive damsels and predators should be avoided.
Reef compatibility
As with the genus, it does not damage corals but may eat small ornamental invertebrates and worms.
Conservation status
IUCN Red List: Least Concern (assessed 2007).
Golden Wrasse Breeding Guide
Overview
Halichoeres melanotis is recorded by FishBase at 13.0 cm TL and occurs in the Eastern Central Pacific from Mexico to Costa Rica, including Cocos Island, at depths of about 8 to 37 m and a preferred temperature near 24.6-28.7 C. It is a yellow-bodied wrasse that, like its congeners, buries in sand at night. It is not bred in home aquaria.
Sexing
Members of this genus are protogynous hermaphrodites that begin life as females (initial phase), with the largest individuals capable of changing into terminal-phase males. FishBase does not list a documented sex-change length for H. melanotis specifically, so practical sexing relies on the size and colour-phase development typical of the genus rather than a verified species-specific marker.
Conditioning
No validated home-conditioning protocol exists. The carnivorous diet of small benthic invertebrates can be matched with varied meaty marine foods in captivity, but conditioning a pelagic-spawning reef wrasse for reproduction has only been pursued in dedicated aquaculture, not in hobby tanks.
Breeding Setup
There is no documented domestic breeding setup. FishBase records distinct pairing during breeding. The fish needs reef structure and a deep sand bed for burying, and the open water column required for pelagic spawning ascents cannot be reproduced at home; the knowledge-base minimum of 200 L reflects husbandry rather than a spawning configuration.
Spawning Behavior & Trigger
In the wild, labrid spawning is a broadcast event: a pair or group ascends and releases planktonic eggs into the water column, dispersed by currents, with no parental care. Spawning is governed by photoperiod, tide and harem social dynamics, none of which are deliberately controllable in an aquarium.
Egg & Fry Care
Eggs and larvae are pelagic. No larval data is published specifically for H. melanotis, but rearing of the congener Halichoeres melanurus describes eggs of about 660 um and larvae of roughly 2.5 mm at hatch settling near 22 days post-hatch on cultured live prey, illustrating the small egg size and demanding live-feed needs of the genus.
Common Challenges
The main challenge is that broadcast-spawned planktonic eggs cannot be captured and the long-lived larvae cannot be fed in a display tank, while the protogynous social system requires a stable harem. Home propagation of H. melanotis is therefore not currently achievable.
