Common name: Red Sea parrotfish
General information
The Rainbow Parrotfish, Scarus collana, is a vibrant and colorful species known for its significant role in coral reef ecosystems. As a member of the parrotfish family, it is recognized for its beak-like teeth, which are used to scrape algae and dead coral, aiding in bioerosion and the production of sand. This species is relatively large, with mature individuals displaying a kaleidoscope of colors that can make them a stunning addition to spacious home aquariums.

Care
Rainbow Parrotfish require large tanks with plenty of swimming space and robust filtration systems due to their size and the amount of waste they produce. They are best suited for fish-only or fish-only-with-live-rock (FOWLR) setups, as their feeding habits can be destructive to coral reefs in captivity. A varied diet that includes algae, marine-based plant matter, and occasional meaty foods will help maintain their health and coloration.
Reproduction
In the wild, Rainbow Parrotfish are protogynous hermaphrodites, starting life as females and potentially changing to males as they mature. They exhibit complex social and mating behaviors, often forming harems. Reproduction in the home aquarium is rare and challenging, requiring a large, well-established system and expert care.
Habitat
Rainbow Parrotfish are found in tropical and subtropical waters, typically frequenting coral reefs, seagrass beds, and mangrove areas. They play a crucial role in their natural habitat by grazing on algae and helping to prevent algal overgrowth on corals. In the aquarium, providing a similar environment with ample hiding places and open areas for swimming is essential for their well-being.
Geographical distribution includes the Western Atlantic from Florida, USA and the Bahamas to Brazil, including the Gulf of Mexico and the Caribbean Sea.
