The Shaggy Anglerfish (Antennarius hispidus), also known as the Hispid Frogfish, can be found among the reefs and lagoons of the Indo-Pacific Ocean. Their colors may range from beige, yellow, orange and red. Their body is adorned with small tassels that give it the appearance of algae or seaweed. They are ambush predators, motionlessly hiding in plain site, waiting for small fish or crustaceans to approach. This being said, they should not be housed with small reef fish or prized crustaceans. They do best in aquariums with plenty of rocks or coral to hide among. They may require live food at first, though many can be trained to eat frozen food in time.     The Care Guide for the Shaggy (Hispid) Anglerfish  The Shaggy Anglerfish, scientifically known as Antennarius hispidus, is primarily found in the warm tropical waters of the Indo-Pacific region. It inhabits shallow coastal areas, often hiding among coral reefs, rocky substrates, or sandy bottoms. Its natural habitat consists of crevices and caves, where it relies on mimicry and camouflage to blend in seamlessly with its surroundings.  Reef Compatibility of the Shaggy Anglerfish: Caution in Reef Environments  Caution is advised when considering the Shaggy Anglerfish for a reef aquarium. They are not regarded as reef-safe due to their predatory nature. These stealthy hunters may consume smaller fish and invertebrates in reef environments. Therefore, keeping them in a fish-only or predator-specific tank is best.  Size and Lifespan of the Shaggy Anglerfish: Small Predatory Marvels  Shaggy Anglerfish are relatively small, with adults typically reaching a size of 7 inches. They can live up to 5 to 7 years in captivity with appropriate care and a suitable environment.  Diet in Captivity of the Shaggy Anglerfish: Small Shrimp and Crustaceans  These anglerfish are carnivorous predators known for their voracious appetites. In captivity, they thrive on a diet of small live or frozen foods, such as brine shrimp, mysis shrimp, and other small crustaceans. Feeding should be done every 2-3 days to ensure they receive proper nutrition.  Aquaculture and Availability of the Shaggy Anglerfish: Check with Reputable Suppliers The Shaggy Anglerfish is not commonly aquacultured, making it less frequently available in the hobbyist market. However, checking with reputable suppliers like Saltwaterfish.com for the most current availability is essential.  Compatibility of the Shaggy Anglerfish with Other Fish and Invertebrates: Solitary Predators  Shaggy Anglerfish are solitary creatures and should be housed alone or with similarly-sized and aggressive tank mates. Avoid pairing them with smaller fish or peaceful invertebrates, as they may become prey. Suitable tank mates include lionfish, groupers, and other non-aggressive, predatory species.  Sexual Dimorphism of the Shaggy Anglerfish: Minimal Differences  Sexual dimorphism in Shaggy Anglerfish is minimal, making it challenging to distinguish between males and females based on physical characteristics. In a captive setting, it is often necessary to consult an experienced aquarist or rely on breeding behavior to determine the gender of the fish.  Juvenile to Adult Coloration Changes in the Shaggy Anglerfish: Masterful Camouflage  The Shaggy Anglerfish displays excellent camouflage, with coloration and skin texture that mimic its surroundings. While juveniles often exhibit more vibrant colors and intricate patterns, adults tend to adopt a mottled appearance, blending in seamlessly with the substrate.  Temperament of the Shaggy Anglerfish: Sedentary Predators  These anglerfish are generally sedentary and have a calm disposition. They spend most of their time waiting for prey to approach their position, relying on their unique lure to attract unsuspecting prey. Their peaceful demeanor makes them suitable for tanks with other aggressive species.  Tank Requirements for the Shaggy Anglerfish: Creating the Perfect Habitat     Minimum Aquarium Size: A suitable tank for a Shaggy Anglerfish should be at least 60 gallons, providing ample space to move and hide.   Water Conditions:       pH: Maintain stable water parameters with a pH of 8.1 and 8.4.    Salinity: Keep the salinity level at 1.020 to 1.025.    Water Temperature: Maintain a temperature range of 75°F and 82°F.    Water Flow: Moderate water flow is ideal.       Common Names: Hispid Anglerfish or Shaggy Frogfish In some regions, the Shaggy Anglerfish may also be called the Hispid Anglerfish or Shaggy Frogfish. …
