Aside from picking the lice off yourself the only known med. remedy for
lice is Potassium promanganate, hope I spelled that right, bad thing is
you can only get it from a chemical company. I had this same prob a few
years ago, the goldfish were covered in lice, I tried to no avail to rid
them by taking tweezers and and removing as much as I dared stressing
the fish to do so. It's almost a no win situation with water lice. Mine
also had anchor worms and I did rid them of that but they were literally
infested with lice and had to be humanely put down. Since you've only
seen 1 lice, just watch closely and remove anymore asap. Good luck I
know it's very stressful when one of your beautiful GF is sick.
