Sargocentron

Sargocentron spiniferum

(Forsskal, 1775)

Giant Squirrelfish, Duckbill Squirrelfish

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Indo-West Pacific Ocean: Red Sea and East Africa, to the Hawaiian Islands, north to Southern Japan, and south to Australia.

Size: 16 inches (40 cm)

Natural Environment: Inhabits caves and crevices in lagoons, reef flats, and seaward reefs during daylight hours and can be found at depths between 3 - 400 feet (1 - 120 m), and feeds mainly at night on crabs, shrimp and small fishes.

General Husbandry: Rarely seen in the trade, having a body shape quite different from others in this genus, as it has a ‘high,’ reddish body.

The largest in this genus, and best maintained in aquariums with several caves/hiding areas large enough to house the adult-sized specimen, as those in this family grow to adulthood quite fast. The aquarium should also be dimly lit, as this is a nocturnal species, preferring to hide throughout daytime hours and feed at night. If maintained in a brightly lit aquarium, i.e., reef aquarium, it should also have sufficient caves as noted above, but will be far less visible in daylight hours. Tankmates must be large enough not to be eaten, as they will also consume smaller fishes.

Requires a meaty diet such as enriched chopped fish or shrimp flesh, mysis, frozen brine shrimp, and/or frozen carnivore foods with one or two feedings per day.

May be difficult to feed in the early days in the aquarium due to its nocturnal feeding habits, and if so, live foods, e.g., live enriched brine shrimp, grass shrimp, black worms (Lumbriculus variegatus), baby mollies and/or guppies should be offered. Over time, it will learn to accept frozen foods like mysis, krill and brine shrimp more readily when offered to others in the aquarium.

Taxonomy:

    Order: Beryciformes

FYI: Will eat ornamental shrimp.

Sensitive to tapping on aquarium side panels.

Has spines on their head and gills, which can come entangled in nets and also a large preopercular spine, which can inflict a wound if mishandled by the aquarist.
