I noticed this morning that right on the tip of Rainbows tail fin, there is a bright red spot.

I don't know what could have caused it. There is nothing for him to catch his tail on.

I thought maybe ammonia, but when I checked it, it was 0.

He has a bubble nest going on. But seems to be resting a bit more than usual. He is very hungry, so his appetite is good.

Why do you suppose that he would get a red spot. It's small, like a pinprick of blood. He actually has a few all in the same spot.

What should I do? Just hope that it goes away, or is there something more I could be doing?

Thanks

Usally when we get blood spots in are eyes ect ect
it goes away and it doesn't hurt or harm the fish.
Just keep a close eye on it and if it gets worst
come and tell us Maby can it be ammonia? thats the only
other thing i think it could be.

Does he rest on the bottom to sleep? My goldfish Pegasus get little blood spots on the very tip of his tail every now and again, and I have begun to think that it is from his tail resting on bottom at night.

If your water quality is good (and I am sure it is ) I would keep an eye on it for a few days and see if it improves.

Let us know and we will go from there.

Thank you! Rainbow does sleep on the bottom!

I will definitely keep an eye on it. It is not any better today, but it's not any worse.

He seems fine, other than the red spot has me worried

Touchofsky, that made me feel a lot better, to know that it may just be from sleeping!

Black Oranda, there is no ammonia present. That was my first thought too!!

Do you ever notice fuzzies stuck to the ends of the tail? When there's even the smallest bit of 'crud' on the tank I can guarantee that it will gravitate toward big flowy fins, and causes sort of centralized finrot, but goes away quickly on its own. I have this problem especially with a superveil angelfish!

You could suck up little pieces of poop and flufffies from the tank every day if you're very worried about it. It's not good for them, but the blood won't cause any serious problems either. I'd also recommend you dose bettafix at this time just in case.
