It's okay Lucky's done similar things XD and I have freaked out.
Once she had a piece of pea sat in her mouth, I could actually see it there and was worried she would choke, it was gone after a few minutes. Then the other day she bit off more than she could chew, she struggled a little, chomping like crazy and I was like 'this is it, I've killed my fish with a pea!' then she spat it out and ate it back in again, she did this a few times, till I managed to get in there and bat her away from the pea. But noticeably the piece of pea was a lot smaller, so I guess eating it in that fashion was easiest for her
I just panicked because it looked like she was struggling, but she knew what she was doing
If anything ever does seem stuck, I've read about people using tweezers to get things out. Plus with the fish so used to you, you could always gently hold them or lift them out of the water and try to remove what ever it is.
