Pearl Scale Needs Help!!

Question
As of this morning, my pearl scale goldfish is having a great deal of trouble swimming and maintaining upright. She can swim for a few seconds before succumbing to an upside-down position.  I have given her a pea, more because she likes them than because I thought it would help and she ate it.
Is there anything I can do to help her?

Thank you for any advice you can offer.

Answer
I'm so sorry it took me so long to get back to you. i lost my internet connection for awhile. The best thing you can do is a water change and food. Make sure her water is clean, beyond that point it's really hard to tell what might be wrong. I'm sorry I can't be of more help. You might want to call a vet and ask..even fish to get sick, and they might be able to give you information that I can't. Good luck!
