Yellow Box fish

Yellow Boxfish are cube-shaped fish with bright yellow coloration and black spots. They live in tropical and temperate marine waters at depths of 1-40 metres and inhabits coral and rocky reefs. They grow to 45cm in length.

The adult yellow boxfish possess dull yellow coloration with brown spots and are often solitary and occur on deeper coastal slopes, lagoons and areas where there are crevices and ridges for shelter.

They feed on molluscs, crustaceans, fishes, sand-dwelling polychaete worms and algae and use their mouth to blow tiny jets of water into the muddy or sandy bottom, stirring the small invertebrates to feed on them.

When stressed or injured it releases poisonous proteins from its skin called ostracitoxin from its mucous glands that may prove lethal to any fish in the surrounding waters. The bright yellow colour and black spots are also a form of warning coloration. 

Yellow boxfish are solitary animals. Breeding occurs during the spring, in small groups that consist of 1 male and 2 – 4 females.
