Anchor worm in Reef Tank

[Dangerousmeg]

I brought in a new fish who started showing signs of anchor worm three days after being introduced to the main tank.

The sick fish is a maroon clownfish. I have a small damsel, a yellow tang, and a coral beauty angel as well as xenia, mushroom corals, coral shrimp, hermits, emerald crabs, and snails.

The clownfish is hiding in the caves of my live rock and I don't know how to treat the main tank without killing my inverts.

Suggestions?

You are going to need to catch the fish. Anchor worm (a parasitic copepod actually) can be physically removed with tweezers or chemically with Clout. The Clout is an organophosphate insecticide that is well tolerated by most fish, but would be a major problem in a reef tank, so treating in a Quarantine Tank (QT) is essential.
