Hi, I've been keeping a common goldfish for about a year now. He lives alone in a planted 10gal with a HOB filter.

He's had this single red dot on his side since I got him. Its about the size of a scale, and it doesn't seem to be hurting him, but I am still slightly concerned.
What could it be?

Any help is appreciated. Thank you.

Dear fish, help us, what should we do?

Keep in mind that goldfish come in many colors. that red spot is just a tiny pinch of ohne of those colors.as they age they may change colors completely.

It is natural as we know about change of hormones, so it may be due to that.
