Abstract:The feeding ecology of two sympatric gobies, Favonigobius lentiginosus and Favonigobius exquisitus, which inhabit soft substrate pools was studied in Moreton Bay, Australia. Favonigobius spp. and sediment cores were collected from three locations within the bay and fish gut contents were analysed to explore potential competition and ontogenetic dietary shifts. The most abundant prey at all sites was nematodes at 6·33 ± 0·38 cm−3 at Dunwich, 33·58 ± 0·26 cm−3 at Manly and 6·36 ± 0·849 cm−3 (mean ±
