Common Name: Commerson's / Giant / Colored Angler Frogfish

Species Name: Antennarius commerson (Latreille, 1804)


Range: Indo-Pacific Ocean: Southern Africa to the Red Sea, and east through the Pacific and north to southern Japan


Size: Up to 12 inches (30 cm)


Natural Environment: Inhabits hard substrates on shallow fringing reefs and gentle sloped areas from depths of 3 - 160 feet (1 - 50 m)


General Husbandry: Has a temperature of 72 - 80°F (22 - 27°C). One of the more colorful frogfish and capable of changing its colors. Will sometimes assume the color of the object it is near to enhance its camouflage. Requires a meaty diet of live shrimp, small fishes, or an enriched diet of defrosted marine flesh. Since these are sedentary fishes, their metabolism is quite low. Therefore, infrequent feedings of once or twice a week for adults and three or four times a week for juveniles is highly recommended. Small live fish/shrimp, preferably marine species, or frozen foodstuffs suspended/impaled on a long stick will suffice. This species, which is one of the more commonly seen in the trade, is one of the largest frogfishes, therefore should be maintained in an aquarium no smaller than 100 gallons and of course without eatable tankmates.
