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.
Even though these fish enjoy a diverse type of frozen foods, it is imperative that its primary food, is algae based, thus ensuring that the fish`s immune system remains healthy.
This can, for example, be plant based fish flakes, Nori seaweed or similar.
This species can change gender from female to male.
When a male is needed, a female changes sex and takes on the role.
Any number of specimens
This species can function in large numbers down to just one.
This species often has a fun and interesting personality.
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.
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.
