Ogcocephalus

Ogcocephalus darwini

Hubbs, 1958

Galapagos Batfish

Not Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Southeast Pacific Ocean: Galapagos Islands to Peru.

Size: 8 inches (20 cm)

Natural Environment: Inhabits sandy and rubble covered bottom areas at reef edges and usually found between a depth of 3 – 400 feet (1 – 120 m). Feeds mostly at night on crabs, worms, snails, bivalves and small fishes.

General Husbandry: Has a mottled brown body and fins. Not puposely collected for the trade, however, ocassionally finds its way into the trade when dredged up by fishing trawlers. It’s a bottom dweller and feeder, often covering its self in substrate.

Requires a wide-open sandy bottom environment, preferably dimmly lit, with little or no decore, as it can injure itself when bumping into decor or even that of aquarium side panels.

As to diet, small pieces of fresh fish and/or crustacean flesh (they have small mouths) impaled on a long feeding stick and waved near its head will usually entice it to grab the food, and should be offered once daily.

May be difficult to get feeding, and if so, live foods, e.g., live enriched brine shrimp, grass shrimp and/or black worms (Lumbriculus variegatus) should be offered.

Taxonomy:

    Order: Lophiiformes

    Suborder: Ogcocephalioidei
