Comprehensive Guide: Blue Hippo Tang (Paracanthurus hepatus)
The Blue Hippo Tang, also known as the Regal Tang or Palette Surgeonfish, is native to the Indo-Pacific region. They are commonly found in coral reefs, lagoons, and outer reef slopes. These fish prefer areas with abundant coral growth and clear water.
The Blue Hippo Tang is generally considered reef safe. However, they may nip at corals, especially if not provided with enough algae and other vegetation in their diet. It is important to monitor their behavior and provide them with suitable food options to minimize any potential coral aggression.
The Blue Hippo Tang can grow up to 12 inches in length, making it a relatively large fish for a home aquarium. It is important to provide them with a spacious tank to accommodate their size.
The Blue Hippo Tang is known to be a semi-aggressive fish. They may exhibit territorial behavior, especially towards other tangs or similar-shaped fish. It is recommended to introduce them into the aquarium last or provide ample hiding spaces to minimize aggression.
There are no distinguishable physical differences between male and female Blue Hippo Tangs.
Blue Hippo Tangs found in the Indian Ocean can have a regional variation of developing a yellow belly once matured. Despite the difference in coloration, they are the same species and have the same care requirements.
In proper aquarium conditions, the Blue Hippo Tang can live up to 10 years or more with proper care and maintenance.
Diet in Aquariums
The Blue Hippo Tang is a herbivorous fish that primarily feeds on various types of algae in the wild. In captivity, their diet should consist of a variety of dried seaweed, algae-based pellets, and live/frozen foods rich in vegetable matter. It is important to provide them with a balanced diet to maintain their health and vibrant coloration.
When setting up the aquarium for a Blue Hippo Tang, it is important to provide ample swimming space and hiding spots. Incorporating live rock structures and creating open areas will allow them to swim comfortably while also providing hiding places to reduce stress. Additionally, ensuring the presence of live rock will help promote natural grazing behavior.
Captive Bred Availability
The Blue Hippo Tang is not commonly available as a captive-bred species. Most specimens in the aquarium trade are wild-caught. However, efforts are being made to develop captive breeding programs for these fish to reduce the impact on wild populations.
Compatibility with Other Fish, Invertebrates, or Corals
The Blue Hippo Tang can be compatible with a variety of tankmates, but caution should be exercised when selecting companions. It is best to avoid keeping multiple tangs of similar size and shape together as they may become aggressive towards each other. Suitable tankmates for the Blue Hippo Tang include:
- Ocellaris Clownfish: These fish are peaceful and can add vibrant colors to the aquarium.
- Yellow Tang: They have a similar shape but are not aggressive towards Blue Hippo Tangs.
- Bicolor Blenny: These small, peaceful fish can add diversity to the tank.
- African Flameback Angelfish: They are relatively peaceful and can coexist with the Blue Hippo Tang.
- Green Mandarin Dragonet: These fish are non-aggressive and add a unique aesthetic to the aquarium.
