Care
Black Hamlets are moderately easy to care for in a home aquarium. They require a tank with plenty of live rock for hiding and hunting. These fish are carnivorous and thrive on a diet of small fish, crustaceans, and various meaty foods. It's important to maintain high water quality and stable conditions to keep them healthy.
Reproduction
In the wild, Black Hamlets are known for their unique spawning behavior, where they engage in a mating dance with their partner before releasing eggs and sperm simultaneously. This fascinating behavior is rarely observed in home aquariums, but with the right conditions, it is possible to encourage breeding.
Habitat
Black Hamlets are typically found in coral reefs and rocky substrates in the Caribbean Sea, the Gulf of Mexico, and the northern coast of South America. They prefer shallow waters, usually not deeper than 30 meters.
Geographical distribution includes areas from Florida and the Bahamas to the northern coast of South America, including the Caribbean islands.
