Main predators are sharks, manta rays, & larger bony fish.
2nd largest member of Zebrasoma genus.
Important in keeping reefs healthy due to algae-eating diet. Without these fish, algal overgrowths can occur.
They’re very active fast swimmers.
Spawn in pairs/groups w/ eggs/sperm being released simultaneously.
Eggs hatch 1 day after being laid. 1st, larvae develop serrate ridges on head, then pelvic fin/2nd dorsal spines form followed by 2nd anal spine. Then head/body deepen becoming kite-shaped w/ long pelvic/dorsal/anal spines. Then triangular scales appear in vertical rows. Finally, juvenile coloring starts showing along w/ tail fin base forming little scalpel.
They reach maturity at a year old.
Can spawn all year round.
Active during the day (diurnal).

Fun Fact(s):
Also called Sailfin Surgeonfish, Pacific Sailfin Tang, Indo-Pacific Sailfin Tang, Eastern Sailfin Tang, Ringed Tang, Ringed Surgeonfish, Sailfish, Pacific Sailfin Surgeonfish, & Purple-Lined Tang. Gets surgeonfish name from sharp scalpel-like spine on each side of tail base used in defense. These scalpels can cause nasty wounds. Gets sailfin name due to appearance of fins & ringed name due to banding.
Besides using tail scalpels in defense, they’ll also use them in territorial fights.
Can store fat in body cavities meaning they can go through short periods of time w/o food.
These fish sometimes called “sea cows” due to eating lots of food/producing lots of waste.
They’re fairly popular in aquarium trade but very difficult to breed in captivity.
Though mostly light-colored, they can darken if under stress.
