The Hippo Tang, also known as the Regal Tang or Paracanthurus hepatus, is a popular and vibrant marine fish species. It is most recognizable for its striking blue body with contrasting black and yellow accents.

While the Hippo Tang is a magnificent addition to any aquarium, it requires more care and attention compared to other fish species. It is recommended for experienced hobbyists or those willing to provide the necessary care it needs to thrive.

Being a herbivorous fish, the Hippo Tang's diet should consist mainly of high-quality marine algae and seaweed. Offerings of dried seaweed, spirulina flakes, and other herbivorous pellet foods are essential to fulfill their nutritional requirements. Supplementing their diet with occasional protein-based foods like mysis shrimp or brine shrimp is also beneficial.

Hippo Tangs can be semi-aggressive, especially towards other tangs or similar fish within the same species. Keeping them in a large tank of 75 gallons or more is advisable to provide ample swimming space and to help minimize potential territorial disputes. Additionally, providing plenty of hiding places and creating visual barriers, such as rock formations, can help reduce aggression.

When it comes to reef compatibility, the Hippo Tang is generally considered reef-safe. However, it may nip at certain corals or sessile invertebrates. Monitoring their behavior and the specific dynamics of your reef tank is crucial to ensure compatibility and prevent any damage to delicate corals or other invertebrates.

Maintaining stable water parameters within the ranges of 72-78°F (22-26°C) for temperature, pH of 8.1-8.4, and specific gravity of 1.020-1.025 is important for the well-being of the Hippo Tang. Regular water changes and effective filtration systems are necessary to maintain excellent water quality.

With proper care, attention to their specialized dietary needs, adequate tank size, and suitable tank mates, the Hippo Tang can be a stunning centerpiece in your marine aquarium, showcasing its beauty and captivating swimming patterns.
