after reading this then there is a possibility that the injury became infected so using the packet is a good thing.. hope it is in time..good luck..
What happened to this fish?

I just culled it. Very sad. Had this fish for over three years.
Now the question becomes what to do about the rest of the tank. It's a 220. Everyone else is healthy but the eartheaters' tail fins aren't as long and flowing as they have been in the past. I wonder if they're all carrying it but are generally strong enough to be OK. 220 gallons worth of erythromycin treatment will put me in the poor house though... Does anything else work for a general gram positive preventative bath? I don't have any oxytetracyclin or anything else that I know as a gram-positive treatment. I also don't understand how this was introduced. This tank has been kept up very well for a long time. (Ever since getting discus all the other fish have gotten meticulous upkeep too. Me getting discus was the best thing that ever happened to the other tanks.)

Do you still have the fish? If you do, do a necropsy to see what the gills and internal organs look like. Look for white nodules. I'm not convinced this is nocardia. Really the only way nocardia could be introduced is if you fed some raw fish or something similar. As far as treating other fish, sulfa drugs such as API triple sulfa are the treatment of choice, and minocycline in maracyn 2 would be your next choice.
To the best of my knowledge Sulfas are generally most effective against aerobic gram-negative bacteria but are not generally effective against aerobic gram-positive bacteria. Minocycline, is a broad spectrum tetracycline type antibiotic, with a broader spectrum than other members of this family, especially gram negative bacteria. This is what I’ve always understood any way. However a broad spectrum antibiotic effective against both might be a good first choice.
I’m not a Veterinarian and I’m only conveying my experience, your fish showed exactly what I encountered a few years ago and the Erythromycin worked. However I’m not going to challenge a Veterinarian when it comes to the correct use of medications, the last thing I want to do is give bad advice.

Sulfonamides are broad spectrum as well, and are particularly effective against nocardia.
If you can't do a necropsy, at least pull back the operculum (gill cover) and look at the gills for white nodules.
