Help!!! I think I have velvet

[s1214215]

Hells bells.. I think my reef has velvet (Amyloodinium ocellatum). Only it looks like velvet , but my fish are still alive after nearly 2 weeks. As I understand it this disease is supposed to be a quick death.
I have 1 premnas clown, 1 friedmanii dottyback, 2 fire gobbies, a nox angel and and bicolor angel and 1 mandarin. The angels seem to be well dusted - yet they are not scratching or breathing badly. The dottyback is scratching periodically, yet seems otherwise normal, as does the mandarin which is not scratching, but has the occaisional chasing its tail episode. The fire gobbies seem totally uneffected as does the premnas clown (does the anemone protect it?).

I have 3 Lysmata debelius (fires shrimps) that the angels spend much time with. The dottyback however does not.

Ok.. what to do. Is this velvet - it sure looks like it (dusty white covering over the fished body with a little muccus). Just no rapid breathing. How do I treat this in a reef (with anemonses, clams, and inverts) when I cant catch the fish without taking my reef down and I have only limited access to medications here. If am going to that trouble I would rather euthenase the sick ones to put them out of their misery and let the tank fallow for a few months (is this a guaranteed method to rid the tank of the pest). If I was to follow the later course of action, would I be able to keep the clown and gobbies that are (seemingly) unaffected.

Help.. I have never dealt with this pest before.. What can you suggest. To medicate or.....
