This occasionally schooling species inhabits sandy bottoms of reef flats, lagoons, coastal and seaward reefs (Ref. 9710, 90102). Benthopelagic (Ref. 58302). In large inactive aggregations by day, dispersing to sand flats to feed at night (Ref. 9710). Sometimes mixes with blue-striped snapper Lutjanus kasmira and shows blue stripes (Ref. 48636). Feeds on small worms and crustaceans. Also caught using ringnets (Ref. 5213). Minimum depth reported taken from Ref. 30874.
