Don,
As with all of the bait they take, they grab it and pull it under water then try to eat it. My tilapia are for the most part to small for the apple to be effective yet. I was using a long shank hook for the pacu and its weight required a fairly large piece of apple. Plus the apple I was using was firm. The fish would repeatedly grab the bait amd pull it under and it would resurface shortly there after, unless it was one of the largest fish, 10". But, their interest was high. Not as high as with the cabbage though. I think I can catch them all afternoon on the cabbage. Hooking and casting it is the real challenge.
