The Butter Hamlet is a popular choice for hobbyist saltwater aquariums, and come in a variety of colors. They are found mainly in coral reefs throughout the Carribean and Gulf of Mexico, particularly around Florida and the Bahamas. Although they are a beautiful addition to your tank, add with caution. They are considered reef safe but will eat other fish and invertebrates. In most cases they will swim freely in the water column and you can feed them frozen brine shrimp.
