The Blue Hippo Tang, also known as the Regal Tang or Palette Surgeonfish, is a popular saltwater fish, especially known for its vibrant blue color and distinct markings. Here are some interesting facts about them:
1. Scientific Name:
Paracanthurus hepatus.
2. Common Names:
Blue Hippo Tang
Regal Tang
Palette Surgeonfish
Hippo Tang
3. Native Habitat:
Found in the Indo-Pacific region, especially around coral reefs in places like the Pacific Ocean, including areas such as Hawaii, Fiji, and the Great Barrier Reef.
4. Appearance:
The Blue Hippo Tang has bright blue, almost electric-colored skin with a yellow tail and a noticeable "scalpel" or spine near its tail, which it uses for defense. The coloration helps camouflage them among coral reefs.
5. Size:
They can grow up to 12 inches (30 cm) in length.
6. Diet:
Blue Hippo Tangs are herbivores, feeding mainly on algae in the wild. In captivity, they should be provided with a diet that includes algae-based foods, spirulina, and other green veggies.
7. Lifespan:
These fish can live up to 10 years or more in captivity with proper care.
8. Behavior:
They are known to be somewhat territorial, especially around their food source, but can be peaceful towards other species. In larger tanks, they tend to do well when housed with other peaceful species.
9. Reproductive Behavior:
They can reproduce in the wild but are not typically bred in captivity. Spawning usually happens in pairs, and they release eggs into the water, where fertilization occurs externally.
10. Care in Captivity:
Blue Hippo Tangs are generally recommended for experienced aquarium keepers due to their size, territorial nature, and dietary needs. They need plenty of swimming space and a well-maintained, stable tank with live rock and proper filtration.
11. Health and Disease:
Like other tangs, they are prone to a disease known as marine ich, which is caused by a parasite. Regular tank maintenance and proper water quality can help prevent this disease.
They also require a balanced diet to maintain their health.
12. In Popular Culture:
The Blue Hippo Tang gained additional fame thanks to the animated film Finding Nemo, where a character named Dory is a Blue Tang.
These vibrant and active fish are admired in marine aquariums for their beauty and lively behavior, but they do require attention and care to thrive.
