Common name: Blackbelly triggerfish

General information

The Wartskin Anglerfish, scientifically known as Rhinecanthus verrucosus, is a distinctive and fascinating species in the reef aquarium hobby. This species is part of the Antennariidae family, commonly referred to as frogfish. They are well-known for their unique appearance, featuring a mottled coloration that can range from greens and browns to more vibrant hues, which helps them blend into their surroundings. Their skin is adorned with various bumps and appendages, giving them a 'warty' look, hence the name.

One of the most intriguing aspects of the Wartskin Anglerfish is its specialized dorsal spine, known as the 'illicium', which is tipped with a lure or 'esca' that mimics prey to attract unsuspecting fish and invertebrates.

Care

Wartskin Anglerfish require a specialized care approach due to their predatory nature and unique feeding habits. They thrive in a well-established aquarium with plenty of live rock for hiding and hunting. It's important to provide a varied diet of live and frozen foods, such as shrimp and small fish, to satisfy their carnivorous appetite. Caution should be exercised when housing them with small fish or invertebrates, as they may become prey.

Reproduction

In the wild, Wartskin Anglerfish exhibit fascinating reproductive behavior, where the male attaches to the larger female and becomes parasitic, eventually fusing with her body. In the aquarium, breeding these fish is quite challenging and rarely observed.

Habitat

Wartskin Anglerfish are found in the Indo-Pacific region, often inhabiting coral reefs and rocky outcrops where they can camouflage effectively. They are benthic creatures, meaning they spend most of their time on the seafloor, waiting to ambush prey.
