Trophic Strategy
provided by Fishbase
Commonly found over mud bottoms in mangrove sloughs and on vegetated sand bottoms, sometimes in brackish water and occasionally also in coral reef areas near mangroves. Feeds on benthic invertebrates (small bivalves, crustaceans), as well as on plant material. Diet were related to size of mouth, change in dentition and habitat. Molariform teeth are nonfunctional in 40 cm SL fishes but are firmly established at 7 cm SL. From 8 cm SL (length at maturity) to 16 cm the fish is omnivorous (Ref. 57616) and demersal in seagrass beds. Above 16 cm SL the fish is 91% carnivorous and demersal in tidal channels (Ref. 42268).
