Itch! Help needed

[Marine_fanaticz]

Hi, newbie here

I have a 10g nano fowlr and have had a healthy clownfish and a hermit crab for about 3 months... Yesterday, I Inteoduced a new clownfish(without quarantine). Now, I can see itch developing on both my clownfish..

So, I would like to ask..

If I remove both clown fishes and put them in a quarantine tank.....Will removing these fishes eliminate the itch in my existing tank? Do I have to remove my hermit crab as well? I don't see any itch on it.

Itch only affect fishes. QT all your fishes frm your DT and leave it fishless for at least month
