Care

Tassled Scorpionfish require a well-structured aquarium with plenty of hiding places and a sandy substrate to mimic their natural habitat. They are ambush predators, so the tank should be equipped with live rock formations where they can camouflage and wait for prey. They prefer a diet of live or frozen meaty foods such as shrimp, fish, and squid. Due to their sedentary nature, they are prone to obesity; thus, feeding should be monitored closely.

Reproduction

In the wild, Tassled Scorpionfish are solitary creatures except during mating. Little is known about their breeding habits in home aquariums, as they rarely breed in captivity. However, in nature, they engage in external fertilization where the female releases eggs into the water column to be fertilized by the male.

Habitat

Tassled Scorpionfish are found in the Indo-Pacific region, from the Red Sea and East Africa to Samoa, and north to the Ryukyu Islands. They inhabit coral reefs and rocky bottoms, often resting motionless and blending in with their environment. They can be found at depths ranging from shallow waters to about 40 meters deep.
