As aquarium fish
Demand a very large aquarium when fully grown
This species needs a very large aquarium when fully grown.
Exactly how big the aquarium should be is hard to say, but the size of this species is such, that it cannot normally be kept in a home aquarium.
This species eats a great deal and demands an aquarium that can tolerate such a heavy load.
Requires plenty of space for swimming.
This species revels in swimming and requires an aquarium with ample space.
This species can change gender from female to male.
When a male is needed, a female changes sex and takes on the role.
This species can eat large amounts of algae (relative to their size) from rocks, like green hair algae and filamentous algae.
As it doesn’t eat every algae type, in case of a specific algae plague, find out more precise information.
Full grown males are blue green with pink markings.
Family description (Scaridae)
Parrotfish (Scaridae) are effective algae eaters for the reef, but some species will also live off rock corals.
Many of these fish will grow too big for most domestic aquaria, although there are some exceptions.
Parrotfish will generally eat a lot and often, which must be taken into account.
It is an advantage to have lots of algae in the aquarium which they can graze on.
These fish will sleep in a mucus cocoon between stones.
The species most often seen in tanks is Scarus quoyi, which is suitable for coral aquaria. It does have a large appetite, so the aquarium must have good filtration.
