Coris

Coris aygula

Lacepede, 1801

Coris Wrasse

Not Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Indo-West Pacific Ocean: Red Sea and East Africa to the Line and Ducie Islands, north to Southern Japan, and south to Lord Howe and Rapa Islands.

Size: 48 inches (120 cm)

Natural Environment: Inhabits sand and rubble patches on outer exposed reefs, lagoon reefs, and seaward reefs and usually found at depths between 6 – 100 feet (2– 30 m) where it feeds on benthic invertebrate, usually hard-shelled invertebrates.

General Husbandry: Occasionally seen in the trade with juveniles highly attractive having a whitish body with small dark spots on the head, two large black spots on the dorsal, with an orange blotch just below each on the upper body and black markings on the dorsal, anal and tail fins. As it grows into adulthood, becomes a drab green.

Best maintained in fish-only aquariums having a fine sand bed, (0.5 – 2.0 mm) and at least 4 inches deep (for juveniles), along with several rocky crevices to hunt and also open swimming areas. Those in this genus will not only rearrange bottom dwelling corals in its search for tasty bottom dwelling invertebrates, as it will eat smaller fishes, snails, tubeworms, sea stars, cucumbers, urchins, crabs, and shrimp that it can find, it will also quickly burrow into the sand bed if frightened or for sleeping at night. This diving into the sand bed will cause clouds of sand particles to be dispensed into the water, and would cause various corals harm, therefore, as mentioned above, those in this genus, depending upon their size, are not often recommended for reef aquariums.

Preferable tankmates are those that are larger and somewhat aggressive, e.g., groupers, angelfishes, hawkfishes, and moderately aggressive triggerfishes.

Requires a meaty diet, including fortified brine shrimp, mysis, and other meaty type marine-based frozen for fresh foods, and should be fed twice daily.

Taxonomy:

    Order: Perciformes

    Suborder: Labroidei

    Family: Labridae

    Genus: Coris

FYI: Cute when small, however quickly grows too large for most home aquariums, and besides, becomes somewhat drab.

Upon first entering the aquarium, may stay buried for days. Simply await its decision when to emerge. Once established, it will go to sleep under the sand and arise the next morning at almost the exact same time every day!

The aquarium should have small pieces of rocks for the wrasse to ‘play’ with in its daily search for prey.

Can greatly stir bottom sandbeds creating large clouds of sand being dispensed in many directions.

Smaller tankmates are at risk of being attacked or harassed as this species grows to adulthood.

Slow swimming tankmates cannot compete with this wrasse at feeding time.
