Using twizzers carefully tear the isopod of the fish. It will leave holes in the fish. Place the fish in a QT for a few days using neomycin as the anti-bacterial medication. Be very carefull with the measurements and do not use charcoal.
After you place the fish back in your tank observe to make sure there are no other isopods

I freshwater/copper dipped the clown to get the pod off before posting the first message.

Do these pods reproduce only on a host, or do I have to QT the whole tank?
(2 clowns, 2 chromis and a mandarin)

Any info would be of great help!!
