If you don't see it often I wouldn't worry about. And typically fsh are able to handle light infestations. Could be a similar species to the yellow grubs that burrow into the flesh of fish. Howver it coud also be part of the cycle of some freshwater clams.

If it's similar to the grub cycle it involves a snail and a fish eating bird like the Great Blue Heron. Keep the herons out and the incidences may disappear in a few years. If you don't have redears already they will control the snails and hopefully the parasite.

If it was me I'd anestisize the fish with a little clove oil in a bucket and then cut it out with a sterilized scalpel or pocket knife. Then release the fish. If you really want to get thorough, pet stores have an antibiotic ointment you can put on the spot you made your cut.

Do some checking on the Koiphen site. Don't be afraid to ask even though your fish is not a koi. You'd be amazed at what knowledge those people have in taking care of their high value koi.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
