Hi everyone, I got my first goldfish the other day, and today I noticed he has red around his mouth. I did some searching around on google and didn't find anything definitive, but I did find this forum and thought maybe I could get some advice for what is going on with my little gold friend. I've put some pictures below that may or may not be helpful. He lives in a tank with normal aquarium gravel and a bubbler, with a plastic plant that I've now taken out in case he was hitting his face on it. If you have any guesses as to what may be wrong, please let me know, I don't want to lose the little guy so soon! Thank you!
