Help My RFA is eating something way to large

[1stPhantom]

So I usually Put in a piece of shrimp with its shell still on it and the tank on Fridays I usually put it underneath a large rock and I put a big about 3 inch piece of shrimp. I guess one of the hermit crabs dislodged it from the rock. I keep it under and go in and see It’s sticking halfway out of it so I go and I try to remove it slowly and carefully, and it has a tight hold on it and started eating it faster will it harm anemone when fully extended is about 3 to 4 inches

If this was my 6-7 in one I wouldn’t be worried per say but the shrimp was a little bigger than the diameter of the Rfa
