I would remove them manually if possible with a tweezers. It is good to
get rid of the adults before they release eggs. the eggs can stand a lot,
as a friend had some infested water dogs in a pool, and 9 months after the
pool was dry stocked it with gambusia, soon they were infested with them.
The anchor worms will pop out when pulled and have a large square "root"
with a "hook" on each corner. I have not lost fish to this method, and
wounds heal quickly. I have had infections on wild caught fish around the
worm, but after removing it, it healed up. This seems to be the year of
anchor worms around here. i have never seen so many, except fishing in
coastal waters of Lake Michigan. Could be something with the weather or
such that promoted them this year. Maybe if that could be figured out, it
could be applied to the aqurium in reverse???
