Commonly referred to as 'Rabbitfish. Probably the most overlooked of fish in the aquarium industry, with species in this group are very diverse in colouration and size. Are a very friendly, efficient herbivore (and will eat many other meaty foods as well) with a diverse range of species that vary in maximum size to suit most aquariums.
Erroneously, they are referred to as not being reef safe, which appears to be a bit of a myth. Some Siganus species have been known to nibble at the odd soft coral. However, any stony coral eating behaviour has not been verified.
Deep bodied compressed fishes with venomous fin spines (wounds from the spines are extremely painful, but usually not dangerous), a small terminal mouth with small closely set incisiform teach, complete lateral line with minute scales. All are diurnal herbivores that feed on benthic algae. Some occur in schools, others as pairs..
