Small crustaceans (Krill, mysis, artemia...)
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.
This species can be found nibbling soft coral and LPS if there is insufficient food available.
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.
This species can live as a pair (male and female).
This species revels in swimming and requires an aquarium with ample space.
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.
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.
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.
|Distribution||Western Pacific: scarcely entering the Indo-Malayan area (except eastern Indonesia), north to Palau and Kosrae, south to northwestern Australia and Tonga (Ref. 43045). Replaced by closely related <i>Siganus virgatus</i> from Sulawesi and the Philippines|

"Minimum volume" indicates the size of the tank needed to house this species under optimal conditions.
This is based on a medium size animal, which you want to keep for several years.
It might be possible to keep smaller specimens for a limited period in a smaller tank. A larger tank might be needed for fully-grown specimens.
"Hardiness" indicates how resistant this species is to disease and how well i tolerates bad conditions in general.
Some species doesn't handle transportation very well, but that doesn't mean that the species isn't hardy under the right conditions.
In this case, a "normal" aquarium is a reef aquarium with mixed corals or a fish only aquarium with an approximately salinity of 1.026 (sg) and a temperature close to 26°C.
Species requiring more than a 4000-liter tank are considered not suitable for home aquarium.
Special aquariums may cover tanks with low salinity, sub-tropical temperature, deep sand bed, sea grass etc.
Always reef safe: No sources indicate that this species will harm corals or other invertebrates.
Often reef safe: Only a few aquarists has reported problems keeping this species with corals and other invertebrates.
Reef safe with caution: This species may be a threat to some types of invertebrates.
Reef safe with luck: Most specimens will harm corals and/or other invertebrates, but you might be lucky.
Not reef safe: This species is a threat to most corals and/or other invertebrates.
