Thanks.... Well, I don't know what to do with her as I don't have a quarantine tank... I can't afford to set one up right now either. :(
As for a veterinarian... I think the cost is just too high, and the odds that the stress taking the fish there and back will kill it, and the likeliness it will not be cured make it not likely to be worth it. :(
2 options I see possible:
Euthanizing her or
Leaving her in the 29g tank.
I could put her back in the 1g tank floating in the 10g tank, but this just doesn't seem like a good long term solution. If the disease is not easily cured, and I know no way to cure it, and it takes a long time to kill the fish, It's pointless to keep her in the 1g tank until she finally dies.
It seems likely to me, that the other fish would have been exposed to whatever disease this is since she was probably in there for a day while she had visible signs of illness - and probably had it evem before that?
I hope it doesn't kill off my entire aquarium's stock...
