Anchor worm problem. Goldfish

[Goldie82]

Hey I'm having a problem with anchor worms. I first noticed one on one of my fish as it appeared as a small "string" hanging from his head. It went away or so I thought and left a red mark on his head. A couple of days later I notice two red marks on his body. One on his side and one on his tail. I also noticed the white worm hanging from both red marks. I now have another fish with an anchor worm attached to his back so I know I have an infestation in the tank. I've read that you can use tweezers to remove but I dont think I want to go that route so I bought cupramine, as advised by my local fish store. I have juSt added this to my tank and am awaiting results. So what should I expect? Will the worms fall off the fish and kill any remaining eggs in the tank? How soon should I see results? Is there anything else I should be doing?

The tank is setup as follows

- 36 gallon tank
- 3 goldfish (smaller size)
- air stone
- canister filter ( carbon removed)
- water tested. With perfect water

Thanks for any advise

How they going? I was thinking extra water changes like ich to help get rid of them but don't know much on these.
