In the present study, the food and feeding habits of lionfish P.volitans, male and female fishes were observed and due to fishes gut contents were analysis. The different food items were recorded from the guts of P. volitans during the study period. Generally, the food items found in the examined gut contents were grouped into eleven different categories. The male fish of P. volitans stomach contents as identified feed compositions in the following order: viz., Crustaceans >Fish >Zooplankton >Phytoplankton >Miscellaneous >Bivalves >Polychaetes >Gastropods >sand >Nematodes >Digested matter and the female fish of P. volitans stomach contents as identified feed compositions in the following order viz., Crustaceans >Fish >Zooplankton >Phytoplankton >Miscellaneous >Bivalves >Polychaetes >Gastropods >Sand >Nematodes >Digested matter, respectively. The present investigation very much useful for this species to be taken up for aquariums in home or office, hotel, hospital, intensive, semi intensive and mass scale culture practices in anywhere in the world.
