As aquarium fish
This species is venomous, but it´s toxin is rarely dangerous to humans. It can however cause considerable pain.
In case of poisoning it is vital to have as much information as possible regarding the species/poison. Have telephone numbers for the poison hotline close to the aquarium.
Since different people can have different reactions to poisons, take precautions necessary to ensure personal safety and that of the surroundings.
This poison can be dangerous if suffering from allergies.
Reef safe, when well fed
This species can be found nibbling soft coral and LPS if there is insufficient food available.
Well established aquarium with algae
These fish should be kept in a well run aquarium where they can "graze" algae from rocks and stones.
If there are insufficient algae on the rocks, it is important to feed more frequently and supplement with algae rich food e.g. Spirulina.
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.
Lives in a pair
This species can live as a pair (male and female).
Changes colour when frightened
This species changes colour when afraid.
Typically, they become pale or brownish.
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 (Siganidae)
Rabbit fish (siganidae) are known for being effective algae eaters.
These fish are often used to fight bubble algae, which can otherwise be hard to remove.
It can be challenging to keep them well fed, if there is not sufficient algae in the aquarium.
They all have toxic spines on their backs, therefore be cautious, although they will mostly swim away and hide, when your hands are in the aquarium. If these fish feel threatened they will hide next to a rock and change colour and pattern. They can appear "ill", but this is their natural camouflage
These fish are not suitable for small aquaria, as they can end up swimming around in the same circle all day long.
