Parrot Fish

Parrotfish - Scaridae

  • Parrotfish continually graze the hard bottom, using their parrot‑like beak of fused teeth to scrape a bite of algae.
  • Often, hard calcium carbonate is ingested with the algae and processed by a second set of plates in the back of the throat.
  • Parrotfish digest the algae and expel the rest through their digestive system.
  • The resulting by‑product is sand! It is estimated that a large Parrotfish can produce over one ton of sand each year.

Feeding: HERBIVORES

Control algae abundance on the reef and keep the hard surfaces clean and allow new corals to grow or invertebrates to attach to the substrate.

There is some evidence that herbivorous fish have bacteria in their guts, much like cows, to allow them to digest more nutrients from the algae.

  • It is assumed that the female release eggs into water columns, which become a part of plankton until they hatch.
  • The eggs begin to hatch 25 hours after being released.
  • Mating occurs year round, but mostly in the summer months.
