open sore again!!!

I suppose they could, DooSPX. It may be putting some pressure on the skin surface from underneath. It might also be a localized pocket of infection that could clear up after breaking open. How long has this been going on? And does it appear to be getting larger?

Usually these sores are caused by aero/pseudomonas bacteria, which often are able to enter the body because of a concurrent fluke infection. Here are a few great sources for treatment options.

Doo, can you post any photos? This sounds like ulcer disease to me.
At the very least I would net the fish, perhaps anaesthetize with clove oil in a shallow tub and dab some bio-bandage or neosporin on the open wound. A wound that has made its way into the muscle of the fish is extremely dangerous and can easily get infected. Prevention is the key as far as that goes. But if you can, post photos first so we can get a good look at the wound.

He's a procrastinator but I will definitely make him take and post photo's when I get home.

Oh, she's beautiful. Very sad to see this happening with her. I hope we can all come up with the right thing to help with her. I expect Flaringshutter or some of the others will know what to suggest. I wish I could offer something more useful, myself, but I'm still learning as I go along too. If that was happening with my fish, I'd be posting the same questions you have... just to be sure.

Like I said, its weird that she is acting fine. eating, darting around, playing with the other fish.

No.. this doesn't surprise me. At least, not anymore. That's just how goldfish are... they really don't show signs of distress to let us have very much to go on when they're diseased or wounded. I wish they did. That would make this a lot easier for us. By the time a dangerously sick goldfish shows changes in behavior, it's almost already too late to properly diagnose those signs and begin treatment. They're so happy, active, and playful all the time - even in bad conditions - that we really can't tell.

Thanks for getting the photos posted for us. That will help narrow this down a great deal. I'll keep watching... see what the others think about this too.

Yeah, that's pretty bad and I'm going to wager that it's a bacterial problem. I definitely recommend treating it manually, so a little anaesthetic to knock out the fish, some hydrogen peroxide or a 7.5% betadine solution to clean out the wound, and then bio-bandage or neosporin to protect and promote healing. Apply with a soft paper towel so you don't get q-tip or cotton ball threads in the wound.
It could be one of many bacterias, so I think the best bet for tank treatment is a Maracyn/Maracyn 2 regimen. Since they are broad-spectrum antibacterials, they should effectively deal with whatever bacteria is causing the problem.
You may want to isolate the affected fish in a quarantine tank or with a divider to keep the other fish from bothering the wound.
Best of luck! And if you need any further help or instructions as far as treatment, feel free to ask. I can provide details

It's meant for scientist-types, but if you can decipher the jargon it's a good read.

Where do you get clove oil?
