Common name: Klunzinger's wrasse

General information

Rueppell's Parrotfish, scientifically known as Thalassoma rueppellii, is a vibrant and active species popular among saltwater aquarium enthusiasts. This species is known for its striking coloration, which can vary from bright green to deep blue, with males typically exhibiting more intense hues and a distinctive yellow stripe along the side of their bodies. As a member of the parrotfish family, they play a crucial role in the health of coral reefs by grazing on algae and helping to prevent algal overgrowth.

Care

Rueppell's Parrotfish require a spacious aquarium with plenty of live rock for grazing and hiding. They are active swimmers and need ample room to move around. A varied diet that includes algae, marine-based flakes, and frozen foods will help maintain their color and health. It's important to note that they may nip at some soft and hard coral species, so they are best suited for fish-only or reef tanks with caution.

Reproduction

In the wild, Rueppell's Parrotfish are protogynous hermaphrodites, meaning they are born female and can change to male later in life. This change is often triggered by social cues or the absence of a dominant male. Breeding them in captivity is challenging and rarely achieved by hobbyists.

Habitat

Rueppell's Parrotfish are native to the Red Sea and the Gulf of Aden. They are commonly found in shallow, coral-rich areas and lagoons, often in small groups. They can be observed grazing on the reef's surface, contributing to the sand production through the digestion of coral.

Their natural habitat includes a range of depths, typically from the shallows down to about 20 meters.
