Fusiliers

Family

The members from the Caesionidae family take their name from the Latin ‘caesius’, meaning greyish-blue and typifying the mainstream colouration of the fusiliers.

The average fusilier is small in size and travels in larger schools. It isn’t particularly comfortable when predators like barracudas or trevallies approach their neighboorhoods. When these predators do, the entire, constantly waving school, will simultaneously and instantly change direction with the velocity of a lashing whip or as swift as a bullet if you like…

A mobile school of fusiliers is always in motion, looking for food. They prefer to do this during the day, diurnal as they are. At night, it rests in areas with hard corals. Their mimetic qualities are amazing. They can, when required, instantly change colour at night among madrepores to blend in with their environment. It does abut on to cleaner stations to perform some sort of symbiotic cleaning acts.

(Blue) Lunar Fusilier

Size up to 28 cm (0,9 ft). Depth up to 20m (65ft)

The sky blue lunar fusilier with its robust and tapering body likes hovering over fringe reefs and reef flats in company in large schools. It eats zooplankton. Divers will get the feeling that sometimes sky blue schools pass by like a hurling wind.

Red Sea/Suez Fusilier

Size up to 25 cm (0,8 ft). Depth up to 20m (65ft)

The Red Sea fusilier is endemic to the Red Sea and hasn’t crossed the Suez Canal yet to enter the Mediterranean Sea . It’s a pretty common species in the northern section of the Red Sea, roaming near outer reef slopes. It can be easily recognised by the white border preceding the black blotch at the tip of the caudal fin. Apart from that, its body has silverish blue tones with white tinges and a white stripe. This diurnal fusilier feeds on zooplankton and finds refuge in coral formations during the night.
