Common name: Spinytooth parrotfish

General information

The Spiny Parrotfish, scientifically known as Calotomus spinidens, is a vibrant and active member of the reef community. This species is known for its striking coloration and the unique ability to change colors and patterns throughout its life stages. Juveniles often exhibit different coloration compared to adults, which can make identification exciting for hobbyists.

Parrotfish are named for their beak-like teeth, which are used to scrape algae from hard surfaces, a behavior that is both fascinating to observe and beneficial for the health of the reef aquarium as it helps control algae growth.

Care

Calotomus spinidens requires a spacious tank with plenty of live rock to graze on and hide among. They are generally peaceful but can be territorial, especially towards conspecifics or similar species. A varied diet that includes algae and marine-based plant matter will help maintain their health and vibrant coloration.

Reproduction

In the wild, Spiny Parrotfish are protogynous hermaphrodites, meaning they start life as females and can change to males as they mature. This aspect of their biology is rarely observed in the home aquarium, as breeding parrotfish in captivity is quite challenging.

Habitat

The natural habitat of the Spiny Parrotfish includes coral reefs and rocky substrates in tropical and subtropical waters. They are commonly found in the Indo-Pacific region, grazing on algae and contributing to the bioerosion and sand production of the reef ecosystem.
