FAQs Answers to the most common questions.
Is a juvenile Twin Spot Coris Wrasse suitable for a typical home reef tank?
Not as a long-term resident, since adult housing calls for at least 300 gallons and the fish matures into a large, active invertebrate predator. Any smaller arrangement is temporary and must be upgraded well before the wrasse reaches full size.
Will it keep its juvenile twin-spot coloration?
No. The pale, spotted juvenile pattern with two dorsal ocelli and orange or yellow highlights gives way to grey, green, or bluish-green adult coloration, and large males also develop elongated dorsal spines and a pronounced forehead hump.
What habitat features are essential before purchase?
A four- to six-inch bed of medium-to-fine sand for sleeping and escape, securely anchored rockwork with crevices, generous open swimming and sand area, and a tight-fitting lid to prevent jumping. The system should be established and sized for the fish's adult activity.
All listed sizes are approximate, not guaranteed, and may vary slightly.
Twin Spot Wrasse – Juvenile (Coris aygula)
The Juvenile Twin Spot Wrasse is one of the most striking wrasses available, displaying a brilliant white body adorned with vivid orange-red blotches outlined in black and a pair of distinctive black "eye spots" on its dorsal fin. Native to the Indo-Pacific, this active species undergoes a dramatic transformation as it matures, developing into a large green-bodied adult with intricate blue facial markings. Intelligent, energetic, and constantly foraging, the Twin Spot Wrasse makes a fascinating addition to large marine aquariums.
Tank Requirements
A 300-gallon or larger aquarium is recommended, as this species can grow to nearly 24 inches. Provide a deep sand bed for burrowing at night, along with sturdy live rock for shelter and expansive open swimming areas. A secure lid is essential, as wrasses are capable jumpers. Stable water quality and ample swimming space are critical for long-term success.
Color, Personality, and Hardiness
Juveniles display a brilliant white body with vibrant orange-red saddles and two prominent black ocelli (eye spots), making them one of the most recognizable juvenile wrasses in the hobby. As they mature, their coloration changes dramatically into shades of green with blue facial markings and intricate patterning. Bold, inquisitive, and constantly on the move, the Twin Spot Wrasse is exceptionally hardy and readily adapts to aquarium life when provided with ample space.
Diet and Feeding
Offer a varied diet of mysis shrimp, chopped shrimp, squid, clam, krill, and other meaty marine foods, supplemented with high-quality carnivore pellets. This active predator also hunts small crustaceans and benthic invertebrates throughout the aquarium. Feed one to two times daily with a diverse diet to maintain excellent health and support growth.
Tankmates and Behavior
The Twin Spot Wrasse is not reef-safe with invertebrates and will prey upon snails, hermit crabs, shrimp, crabs, sea stars, worms, and other small benthic animals. It is generally compatible with medium to large, robust fish but may consume very small fish as it reaches adulthood. Due to its eventual large adult size and active nature, this species is best suited for spacious fish-only systems or carefully planned predator aquariums where its natural hunting behavior can be accommodated.
