When a goldfish swollows gravel - what happens??

[vanderkm]

Thanks for advice Lizzy - the fish is doing fine but I am still worried about long term effects. I don't think the squeeze was hard enough to do damage but can't be sure. How would you suggest restraining him to remove something with tweezers??

He continues to be a real pig about this new food - guards the area on the floor of the tank where it falls until he can get it all. He is the white marked one in the photo.
