Common name: Scarlet Frogfish

General Information

The Scarlet Frogfish or Freckled Anglerfish, scientifically known as Antennatus coccineus, is a fascinating and unique species that captivates aquarists with its unusual appearance and intriguing behaviors. This species is part of the Antennariidae family, known for their remarkable ability to camouflage and their distinctive lure used to attract prey. The Scarlet Frogfish is relatively rare in the aquarium trade, making it a prized addition for enthusiasts seeking something out of the ordinary.

Frogfish are renowned for their incredible camouflage abilities, often resembling sponges or rocks, which allows them to ambush prey with astonishing speed. The Scarlet Frogfish, in particular, is noted for its vibrant red or orange coloration, although it can also display a range of other colors depending on its environment.

Care

Caring for a Scarlet Frogfish requires attention to detail, particularly in replicating its natural habitat. They thrive in aquariums with plenty of live rock and hiding spots, which help them feel secure and provide opportunities for ambush hunting. While they are relatively hardy, maintaining stable water conditions is crucial for their well-being.

Scarlet Frogfish are best kept in species-specific tanks or with very carefully selected tank mates, as they have a voracious appetite and may consume smaller fish or invertebrates. A tank size of at least 100 liters (26 gallons) is recommended to provide ample space for exploration and hunting.

Diet and Feeding

The Scarlet Frogfish is a carnivore with a diet primarily consisting of live prey. In the wild, they feed on small fish and crustaceans, using their specialized lure to attract unsuspecting victims. In captivity, they should be offered a variety of live or frozen foods, such as shrimp, small fish, and other meaty offerings.

Feeding should be done with care, as frogfish can be prone to overfeeding. Offering food every 2-3 days is generally sufficient, ensuring that the prey is appropriately sized to prevent choking or digestive issues.

Behavior and Compatibility

Scarlet Frogfish are solitary and can be territorial, particularly towards other frogfish. They are best kept alone or with larger, non-aggressive tank mates that they cannot easily consume. Their sedentary nature and ambush hunting style make them a unique addition to a marine aquarium.

While they are not inherently aggressive, their predatory nature means they should be housed with caution. Avoid keeping them with small fish or invertebrates that could be seen as prey.

Health and Common Issues

Scarlet Frogfish are generally hardy but can be susceptible to common marine ailments if water quality is not maintained. Regular monitoring of water parameters and ensuring a clean environment can help prevent issues such as ich or bacterial infections.

When selecting a Scarlet Frogfish, look for individuals that are alert and responsive, with clear eyes and intact fins. Avoid specimens that appear lethargic or have visible signs of stress or disease.

Habitat

The Scarlet Frogfish is found in tropical and subtropical waters of the Indo-Pacific region, often inhabiting coral reefs and rocky outcrops. They prefer environments with plenty of cover, such as sponges and corals, which they use for camouflage.

In captivity, replicating this environment with live rock and hiding spots is essential for their comfort and well-being. Providing a habitat that mimics their natural surroundings will encourage natural behaviors and reduce stress.
