Marine Velvet

[wongkwp]

About a week ago, all the fishes im my tank except 2 has died. Before it happen, I noticed that some of my fish has a kind of white-powdery dust on their body, and they swim up above the water adn occassionally scratch thier bodies against the rocks. Well, it was too late until I realized that my tank has been infected with marine velvet. I intend to put the 2 fish (a tomato clown and a damsel) which still survives into a hospital tank for treatment, just in case they too are infected. Do I need to perform hyposalinity to cure them? I still have a turbo snail, a small hermit crab, a camel-shrimp and 2 feather-dusters in my tank. Do I need to move them too to the hospital tank? What do I need to do on my display tank after moving the fishes?

I've already moved the remaining fish to a hospital tank. Do I need to move the rest like the feather dusters and shrimp? I still believe my tank was infected by marine velvet as it has all the symptoms like off-white dust spots on the fish, heavy breathing, strange swimming motion and rubbing itself on rocks. I've even seen more of this off-white dusts on my substrate. As far as I want to save the remaining creatures from dying, I would want to free-up my display tank from the parasites.
