Symphodus tinca, commonly known as the Tordo or Peacock Wrasse, is a species of marine ray-finned fish belonging to the family Labridae. It is a medium-sized wrasse characterized by its robust body, prominent lips, and often vibrant, sexually dimorphic coloration. This species is known for its complex reproductive behaviors, including nest building by males and sequential hermaphroditism. It plays an important ecological role in coastal rocky and seagrass habitats.
Caratteristiche fisiche
- Forma del corpo
- compressed
- Colorazione
- Highly variable and sexually dimorphic. Males are typically more brightly colored, often displaying intricate patterns of green, blue, red, and orange, with iridescent spots and lines. Females and juveniles are generally duller, ranging from greenish-brown to reddish-brown, often with mottled patterns for camouflage. A distinctive dark spot is usually present at the base of the caudal fin and sometimes on the operculum. During breeding, males exhibit intensified coloration.

- Pinna caudale
- Rounded to slightly truncate caudal fin.

- Large, fan-like pectoral fins.
- Pinne distintive
- Pelvic fins are thoracic, located directly below the pectoral fins. Anal fin has 3 spines and 8-11 soft rays.
Consigli per l'identificazione
Body Shape and Size
Look for a robust, compressed body, typically reaching up to 40 cm (16 inches) in length, though usually smaller (20-30 cm).
Coloration and Patterns
Observe the highly variable but often vibrant coloration, especially in males. Look for iridescent spots, lines, and the characteristic dark spot at the base of the caudal fin. Females are generally duller, with mottled brown/green patterns.
Head and Mouth
Note the relatively small, pointed head with thick, prominent lips. The mouth is terminal.
Fin Structure
Examine the single, long dorsal fin with a spiny anterior portion and a soft-rayed posterior portion. The caudal fin is rounded.
Habitat
This species is almost exclusively found in rocky reefs and seagrass beds, which helps differentiate it from pelagic or sandy-bottom dwelling species.
Habitat
- Tipo di acqua
- saltwater
- Profondità
- Typically found in shallow coastal waters, from the surface down to about 50 meters (164 feet), though occasionally deeper.
- Ambiente
- Prefers rocky bottoms, seagrass beds (especially Posidonia oceanica meadows), and areas with mixed sand and rubble. Often found near crevices and caves for shelter. Juveniles may inhabit shallower, more protected areas.
- Areale geografico
- Eastern Atlantic Ocean, from Portugal to Morocco, including the Canary Islands. Widespread throughout the Mediterranean Sea and the Black Sea.

- Compatibilità: Best kept in a species-specific tank or with other robust, non-aggressive temperate marine fish. Avoid keeping with smaller, docile species or ornamental invertebrates as they may be preyed upon.
- Requisiti speciali: Requires a well-established, mature aquarium with ample live rock for hiding and foraging. A deep sand bed is beneficial for burrowing during rest or perceived threat. Excellent filtration and stable water parameters are crucial. Not commonly kept in home aquaria due to size and specific needs.
Informazioni in natura
- Stato di conservazione: least concern
- Stagionalità: More active and visible during warmer months (spring to autumn) when water temperatures are higher and breeding occurs. Can be caught year-round, but fishing activity often peaks in summer.

Fatti chiave
Nest Builderbehavior
Male Tordos are diligent nest builders, constructing elaborate nests from algae and seagrass fragments, which they then guard fiercely.
Sequential Hermaphroditeevolution
Symphodus tinca is a protogynous hermaphrodite, meaning individuals are born female and can later change sex to male.
Cleaner Fish Behaviorbehavior
Juvenile Tordos, and sometimes adults, have been observed engaging in cleaner fish behavior, removing parasites from other larger fish species.
Coloration for Courtshipbehavior
The vibrant and complex coloration of male Tordos intensifies dramatically during the breeding season, playing a crucial role in attracting females to their nests.
Dietary Generalistbehavior
While primarily carnivorous, feeding on small invertebrates, the Tordo is considered a dietary generalist, adapting its diet to available prey in its diverse habitats.
Informazioni di sicurezza
Sicuro- Livello di sicurezza: safe
- Velenoso: No
- Commestibilità: edible
- Note sul maneggio: No specific handling precautions are required beyond standard fish handling practices to avoid fin pricks. The dorsal and anal fin spines are sharp but not venomous. Handle carefully to avoid injury to both fish and handler.
Specie simili
Green Wrasse
Labrus viridis
Generally larger, more uniformly green or brownish-green, and lacks the intricate patterns and prominent dark caudal spot often seen in S. tinca. L. viridis has a more elongated body and a different head profile.
Brown Wrasse
Labrus merula
Typically larger and more uniformly dark brown or bluish-brown, especially in males. It lacks the vibrant, multi-colored patterns of S. tinca and has a more pointed snout.
Ocellated Wrasse
Symphodus ocellatus
Much smaller in size (max 12 cm) and characterized by a distinct ocellated spot (eye-like spot) on the operculum, which is usually more prominent than any opercular spot on S. tinca. Coloration is also different, often with more distinct banding.
