Notolabrus fucicola, commonly known as the Purple Wrasse, is a robust and colorful wrasse species endemic to the temperate waters of southeastern Australia and New Zealand. It is characterized by its variable coloration, often displaying shades of purple, brown, and green, with distinct banding patterns that can change with age, sex, and geographical location. This species plays an important ecological role in its reef habitats as a predator of various invertebrates.
Physical Characteristics
- Body shape
- elongated
- Coloration
- Highly variable. Juveniles are typically greenish-brown with dark bands. Adults can range from deep purple to reddish-brown, often with irregular darker bands or blotches. Males tend to be more intensely colored, especially during breeding, displaying vibrant purples, blues, and greens. A prominent dark spot is often present at the base of the pectoral fin. The head may have intricate patterns of lines and spots.
- Scale type
- cycloid
- Mouth position
- terminal
- Distinctive features
- Thick, fleshy lips, Canine-like teeth at the front of the jaws, Variable banding patterns that change with age and sex, Often a dark spot at the pectoral fin base
- Dorsal fin
- Single, long dorsal fin with 9 spines and 11-12 soft rays. The spiny portion is typically lower than the soft-rayed portion.
- Tail fin
- Rounded to slightly truncate caudal fin.
- Pectoral fin
- Large and rounded pectoral fins.
- Distinctive fins
- Pelvic fins are thoracic, located directly below the pectoral fins.
Identification Tips
Coloration and Pattern
Look for the characteristic purple, brown, or greenish body with variable banding or blotches. The dark spot at the pectoral fin base is a good indicator.
Body Shape
Its relatively deep, elongated body and thick lips are typical of wrasses.
Habitat
Found exclusively in temperate rocky reef and kelp forest environments of southeastern Australia and New Zealand.
Size
Adults can reach a considerable size, up to 50 cm, which helps distinguish them from smaller wrasse species.
Habitat
- Water type
- saltwater
- Depth
- Typically found in shallow coastal waters from 1 to 60 meters (3 to 197 feet), occasionally deeper.
- Environment
- Rocky reefs, kelp forests, seagrass beds, and areas with abundant algal growth. They prefer complex habitats with plenty of crevices and hiding spots.
- Geographic range
- Endemic to the temperate waters of southeastern Australia (from southern Queensland to Tasmania) and New Zealand (North and South Islands).
Aquarium Information
- Care level: advanced
- Temperament: semi-aggressive
- Diet: carnivore
- Minimum tank size: 250 gallons (946 liters)
- Temperature: 14-20°C (57-68°F)
- pH level: 8.1-8.4
- Hardness: 8-12 dKH
- Compatibility: Best kept in a species-specific tank or with other large, robust, and semi-aggressive temperate marine fish. Not suitable for reef tanks due to its predatory nature on invertebrates.
- Special requirements: Requires a large tank with plenty of live rock for hiding and foraging. A sand bed is beneficial as they may bury themselves at night or when stressed. Excellent filtration and stable temperate water conditions are crucial. They are jumpers, so a secure lid is essential.
Wild Information
- Conservation status: least concern
- Seasonality: Can be found year-round, but fishing activity may vary with local regulations and weather conditions.
- Market price: Low
- Commercial importance: low
- Taste: Mild, slightly sweet
- Texture: Firm, flaky white flesh
- Cooking methods: Baked, Grilled, Pan-fried, Steamed
- Nutritional value: Good source of lean protein and Omega-3 fatty acids.
Key Facts
Protogynous Hermaphroditesbehavior
Purple Wrasses are protogynous hermaphrodites, meaning they are born female and can change sex to male later in life, typically when they reach a certain size or when a dominant male is removed from a social group.
Color Variationinteresting
The coloration of Purple Wrasses is highly variable and can change significantly with age, sex, and even mood or environmental conditions, making identification sometimes challenging.
Dietary Habitsbehavior
They are opportunistic carnivores, feeding on a wide range of benthic invertebrates including crustaceans, mollusks, and echinoderms, playing a crucial role in controlling these populations on rocky reefs.
Territorial Behaviorbehavior
Adult males can be territorial, especially during breeding season, defending their chosen areas from other males.
Safety Information
Safe- Safety level: safe
- Venomous: No
- Edibility: edible
- Handling notes: No specific handling precautions beyond standard fish handling. They can deliver a bite if provoked due to their strong jaws and teeth, so handle with care.
Similar Species
Blue-throated Wrasse
Notolabrus tetricus
Males of Notolabrus tetricus typically have a distinct blue throat and head region, and a more prominent dark blotch on the side, which is usually absent or less defined in Notolabrus fucicola. Females are generally more uniformly mottled brown.
Senator Wrasse
Pictilabrus laticlavius
The Senator Wrasse is generally smaller and has a more slender body. Males often display vibrant green and red stripes, and a distinctive black spot on the dorsal fin, which are not present in Notolabrus fucicola.
