Ecology Summary - Siganus corallinus
Ecology of Siganus corallinus
 
Main Ref. Woodland, D.J., 1990
Remarks Smallest juveniles (up to 25 mm SL) live in schools of about 20, often in seagrass beds, feeding on 'aufwuchs' on fronds; at 50 mm SL they live in schools among branching corals in waters about 2 m deep, grazing on finer benthic algae (often form mixed feeding schools with siganids & scarids); at about 60 mm SL, pair bonds begin to form which are partly nomadic & may join large schools which migrate to feed in areas flooded by the tide; by 15 cm SL, pairs are sedentary, living among corals in deeper waters (about 6 m) such as lagoons & drop-off faces at edges of reefs, with coarser benthic algae as their diet. Feeding in crevices facilitated by slightly tubular snout (Ref. 1419). Also Ref. 58534.
