Help Identifying a White Sore on my Goldfish and How to Treat

[Erick 1]

Hi,

Yesterday I noticed a strange white sore on one of my goldfish and I'm trying to identify what it is and how can I treat it?

I have 5 goldfish on a 90/100 gallon pond outdoors, if you need additional information please let me know.

For some reason I cannot insert the image from the option, but here is the link:

Sorry I can't see the photo. If you have it on your computer you can just upload it to the site. you don't need a google drive.

It could be a few things. 

1. bacterial infection

2. a open sore healing 

or other things.

If you can try to get the photo to show up and we can try and help you better
