PhunkeyPhish,
I've heard of this being done several ways. One: just put the fish into the water dish and let the frog do the work. This will not if your frog is like mine are, they never get into their water dish. Two: hand feed it to him. Just lightly run it across his nose once or twice and by the third time you may not have anything to hold anymore! Or third: jsut set the fish down on the ground in front of the frog and let it fop around, before a moments time tha fish will be gone. These are the ways I'm familiar with, others might have other ways, but these are all I know. Good luck with your frog and his taste for sushi!
