This small, colorful fish is known for its striking appearance, with a base color that can range from yellow to green, and often marked with dark vertical bars.

Care
Butter Hamlets are relatively hardy and can be a good choice for intermediate to advanced marine aquarists. They require a well-established aquarium with plenty of live rock for hiding and hunting. These fish are carnivorous and thrive on a diet of small meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood.
Reproduction
Reproduction in Butter Hamlets is quite fascinating as they are simultaneous hermaphrodites. They can pair up and take turns playing male and female roles during spawning. This reproductive strategy can increase the chances of successful fertilization.
Habitat
Butter Hamlets are found in the Western Atlantic, from Florida and the Bahamas to the Gulf of Mexico and the Caribbean Sea. They inhabit coral reefs and rocky substrates, often seen at depths ranging from 3 to 30 meters (10 to 100 feet).
