Feeding behaviour and rearing feasibility of a multipurpose wild goby fish, Glossogobius giuris in backyard ponds has been discussed. The fish shows inclination towards animal diet with wide range of food preferences at various trophic levels. Specimens collected from natural habitat and also from rearing pond indicate its preference towards small sized fishes. The fish is a voracious feeder and exhibit somewhat aggressive behaviour when kept in fasting mode for a period of 12 to 24 hour. Further, the fish prefers mostly in live food, be it small fish, earthworm or mosquito larvae but exhibit little interest towards homemade and commercial fish feed.
