Harlequin Sweetlips (Plectorhinchus Chaetodonoides), also known as Spotted Sweetlips and Clown Sweetlips, is a beautiful and popular fish species among aquarium enthusiasts. Here are some guidelines on how to take care of Harlequin Sweetlips fish:

Tank Setup:

Harlequin Sweetlips need a spacious tank of at least 150 gallons as they can grow up to 2 feet in length. They prefer a rocky reef-style aquarium with plenty of hiding places and open spaces for swimming. The tank should have a sandy substrate and strong filtration system to maintain water quality.

Water Parameters:

Harlequin Sweetlips need a temperature range of 75-82°F (24-28°C) and a pH range of 8.1-8.4. They prefer moderate to high water flow and a specific gravity of 1.020-1.025.


Harlequin Sweetlips are carnivorous and require a varied diet of meaty foods such as shrimp, squid, clams, and small fish. They should be fed 2-3 times a day, with the amount of food adjusted based on the fish's size and activity level.


Harlequin Sweetlips are generally peaceful but can become aggressive towards smaller fish and invertebrates. They can be kept with other larger, peaceful fish such as tangs, angelfish, and groupers.


Harlequin Sweetlips are active swimmers and can become quite curious and interactive with their owners. They have a unique personality and can recognize their owners over time.

Health Concerns: Harlequin Sweetlips are prone to common fish diseases such as ich, velvet, and bacterial infections. Keeping the tank clean and well-maintained is important to prevent the spread of disease. Quarantining new fish before introducing them to the main tank is also recommended.

By following these guidelines, you can provide a healthy and happy environment for your Harlequin Sweetlips fish.
