Thanks for the tips.
I didn't get a picture of it, but looked like an anchor worm. It was about 2-3 mm long with a y-shaped end. She appears fine and I haven't noticed any more on her or the other frogs. There are 6 frogs together in this tank (40 gal breeder), along with a couple fishes. It would be quite a challenge to clean this tank out. I will get a salt tank ready if I see any more.
Been meaning to post some pictures in the photo area.
