I have a very large gold fish who likes to suck the rocks from the tank. He got one stuck in his throat and I wasn't sure how to help him out. I called here and asked what I could do. With out seeing him, they are not allowed to give advise. Totally understandable! But she just suggested trying a Qtip. A few minutes later, we were able to get the rock out of his mouth! About the size of a penny! Thank you for the suggestion!
