Overview
- Commonly known as the Sailfin Tang.
- Native to the Indo-Pacific region, including reefs of Indonesia, Australia, and the Red Sea.
- Distinguished by its striking vertical stripes and large, sail-like dorsal and anal fins.
- Highly valued for its vibrant pattern and ability to control algae in reef aquariums.
Feeding
- Herbivorous diet consisting mainly of marine algae.
- Requires a diet rich in seaweed, spirulina, and high-quality herbivore pellets.
- Providing fresh or dried seaweed on a feeding clip is beneficial.
- Occasionally consumes meaty foods but should primarily have a plant-based diet.
Habitat
- Found in coral reefs and rocky coastal areas with abundant algae growth.
- Thrives in warm, stable water conditions with moderate to strong currents.
- Requires a minimum 125-gallon (473 L) tank due to its large adult size and active nature.
- Needs proper filtration, live rock, and open swimming areas to mimic its natural habitat.
Fish Care
- Optimal water temperature: 74-82°F (23-28°C).
- Ideal pH level: 8.1–8.4, with a specific gravity of 1.025–1.026 (about 33–35 ppt).
- Regular water changes and strong filtration are necessary for maintaining water quality.
- Prone to marine ich and other parasites; a quarantine period is recommended before introduction.
- Requires a stress-free environment with plenty of swimming space and hiding spots.
Compatibility
- Generally peaceful but can become territorial with other tang species.
- Coexists well with a variety of reef-safe fish, such as clownfish, angelfish, and gobies.
- Best kept singly or with different tang species to prevent aggression.
- Providing ample live rock and a spacious tank helps minimize territorial disputes.
Aquarium Behavior
- Active swimmer that requires plenty of open space.
- Frequently seen grazing on algae from rocks and decorations.
- Generally peaceful but may display territorial behavior if space is limited.
- Providing a well-balanced diet and structured environment encourages natural behavior.
Frequently Asked Questions
How does the Sailfin Tang get its name?
It can nearly double its apparent size by raising its very tall dorsal and anal fins.
How big does it get?
Our page lists a maximum length of about 12 in (30 cm).
What size tank does it need?
Our page recommends at least 125 gallons (473 L), and stresses lots of swimming room.
What does it look like?
It has a brown body with five yellow vertical bands and freckles on the snout. Small juveniles have alternating yellow and black bars.
Where is it found?
Its range covers the eastern Indian Ocean to the Pacific, from Christmas Island to Hawaii and Pitcairn. In the western Indian Ocean, the similar Desjardin's Sailfin Tang takes its place.
What should I feed it?
Our page lists it as an herbivore. It eats leafy macroalgae in the wild, so clip dried seaweed in the tank at least three times a week.
Can I keep two together?
It is aggressive toward its own kind. If you want more than one, add them at the same time.
How long can it live?
It can live up to about 27 years.
What water conditions does it need?
Aim for 72 to 78°F (22 to 26°C), pH 8.1 to 8.4, dKH 8 to 12 and a specific gravity of 1.025 to 1.026 (about 33 to 35 ppt).
Is it reef safe?
It is reef safe. It grazes algae rather than corals.
