Indigo Hamlet: The Striped Caribbean Beauty
The Indigo Hamlet (Hypoplectrus indigo) is a striking and hardy marine fish belonging to the Grouper/Sea Bass family (Serranidae). It is highly prized in the aquarium trade for its dramatic and unique coloration, featuring a deep, rich blue to indigo body adorned with several bold, vertical electric blue or white bars. This beautiful pattern helps conceal it in its natural reef habitat.
Native to the Western Central Atlantic, specifically the Caribbean, Bahamas, and Florida Keys, the Indigo Hamlet is a manageable size for many home aquariums, typically reaching a maximum adult length of 5 to 6 inches (13-15 cm). Given its need for territory and swimming space, a minimum tank size of 50 to 75 gallons is recommended.

The Indigo Hamlet is a stunning addition to my reef tank. Its vibrant blue and white stripes stand out beautifully. It’s active and peaceful, and it seems to blend well with the other fish. I’ve kept it for over six months and it’s thriving in a 75-gallon tank.
