General Description
The Redtail parrotfish, also known as the Blue black-finned chub, belongs to the family Scaridae - Sparisoma. These fish are effective algae eaters for the reef, although some species may also consume rock corals. Sparisoma chrysopterum can reach a maximum size of 46.0cm and is distributed in the Western Atlantic, from southern Florida (USA) and the Bahamas to Brazil, including the Caribbean Sea.
Aquarium Suitability
Despite their effectiveness as algae eaters, Redtail parrotfish are not suitable for home aquariums due to their large size and demanding nature. When fully grown, these fish require a very large tank, with a minimum size of 3500 liters. They have a heavy feeding load and need ample space for swimming, which must be considered when setting up an aquarium.
Care and Hardiness
Redtail parrotfish are considered average in terms of hardiness. They require a diet rich in macroalgae (such as seaweed or nori) and microalgae like spirulina. These fish can change gender from female to male, with females transitioning when a male is needed.
Reef Suitability
The compatibility of Redtail parrotfish with reefs is unknown. However, some species of parrotfish may feed on rock corals, so caution should be exercised when considering their placement in a reef tank.
Aquarium Setup
Setting up an aquarium for Redtail parrotfish should involve providing ample space for swimming and grazing. The tank should have good filtration to manage the heavy feeding load of these fish. It is advantageous to have plenty of algae in the aquarium for them to feed on.
Behaviour
The temperament of Redtail parrotfish is unknown, but they are known to sleep in a mucus cocoon between stones. These fish are active swimmers and require a spacious environment to exhibit their natural behaviors.
Feeding and Diet
Redtail parrotfish have a diet that consists of macroalgae like seaweed and microalgae such as spirulina. They are efficient algae eaters and can consume significant amounts of algae from rocks, including varieties like green hair algae and filamentous algae.
Dimorphism and Captive Reproduction
Redtail parrotfish are hermaphroditic and can change gender from female to male. In the captive setting, reproducing these fish may present challenges due to their large size and specific reproductive behaviors.
Habitat and Distribution
Their natural habitat includes the Mexican Gulf and the West Atlantic region. They are commonly found in waters ranging from southern Florida and the Bahamas to Brazil, as well as throughout the Caribbean Sea.
