The Redband Parrotfish is primarily an algae eater.
Redband parrotfish does not get very large only around 20 cm in length.
Diet and Behavior
The redband parrotfish have beak-like mouths used to scrape algae from rocks and coral.
They digest a mixture of coral and algae, the indigestible material is excreted as sand on the reef.
This manner of feeding plays an important role in distributing and manufacturing coral sand in the reef, it also prevents suffocation of the coral by a high concentration of algae.
The redband parrotfish breeding can take place year round and it tends to occur mostly during mornings.
Gametes are released in the water by the female for external fertilization by the male.
This is known as aggregated spawning where the individual rushes upward to release either
sperm or eggs at the peak of the upward dash.
Eggs may be up to 1mm in diameter, spherical and buoyant.
Larvae hatch after about 25 hours.
