I have three gsp :) you can buy frozen food from petland or other fish stores or pet stores. I would avoid the combo meals like "marine fish buffet" or whatever, Mine LOVE mussels and once i tried them on those they would eat little else, however mine do like blood worms and brine shrimp they LOVED krill when i first brought them home but that is because they had never had frozen food now they they have been spoiled with mussels they won't eat krill at all and hardly anything else.. I take that back.. fresh snails are their FAVORITE!!!! they could eat those all day if I would let them. but since they are still juveniles i find i have to smash the snail with a butter knife and then put shell and all in. they still get to nibble on the shell so that helps :) you might watch for signs of parasites or illness. Im not judging you for buying from walmart but because they don't really know anything about fish or fish health it might be possible that its sick. Hope this helped :) hope your puffer starts eating soon :)
