He swims against the glass but I see fish do that all the time. I've never seen him run into it hard. He pecks at the gravel but I've seen goldfish do that and it never looks rough. If it is a wound, how long should it take to heal up? Thanks for the quick reply, any more theories?
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...
