I don't know Cathy, will the lfs re-home them for you?
btw I had a similar experience tonight. One of the small orandas got a pebble in it's mouth that it couldn't spit out. I'm usually of the opinion if it is small enough to get sucked in it will be small enough to spit out, so far that's been the way.
Anyway I watched this little fella struggle for 10mins or so, sometimes he would get the pebble half way out his mouth then it would go back in again. He came over to the front of the tank in front of where I was sitting and just stayed there, I swear he was saying "help me, help me!" So I caught him and tried applying a little pressure around his mouth to 'pop' the pebble out, this didn't work so I used tweezers and out it came easily.
Then he swam off happily, non the worse for wear.
