Common name: Three-spot frogfish

Scientific name: Lophiocharon trisignatus (Richardson, 1844)

General information

The Three-spot Frogfish, Lophiocharon trisignatus, is a fascinating and unusual fish species that captures the interest of many marine aquarists. Known for its unique appearance and incredible camouflage abilities, this species is a master of disguise, blending seamlessly with its surroundings. Frogfish are part of the anglerfish family Antennariidae, which are known for their modified dorsal spine that acts as a lure to attract prey.

Care

Caring for a Three-spot Frogfish requires an understanding of its natural behavior and environment. These fish are sedentary predators that prefer to lie in wait for their prey, so they need an aquarium with plenty of live rock or decorations to provide hiding spots and ambush points. They are not particularly active swimmers, so strong water flow is not necessary. However, water quality should be maintained at high standards, with regular water changes and efficient filtration.

Feeding can be a unique challenge, as frogfish typically eat live prey. Offering a variety of live foods such as small fish or shrimp can encourage natural hunting behavior. Over time, some individuals may be trained to accept frozen or prepared foods.

Reproduction

Reproduction in frogfish is a fascinating process. Males and females come together only to spawn. The female releases her eggs in a gelatinous mass that floats to the surface, where fertilization occurs. The eggs then drift in the plankton until hatching.

Habitat

Lophiocharon trisignatus is found in the Indo-Pacific region, from the Red Sea and East Africa to Samoa, and from the Ryukyu Islands to Australia. They inhabit coral reefs and rocky substrates, often disguising themselves among sponges or corals at depths ranging from shallow waters to about 20 meters.
