velvet treatment advice needed......

[jtbadco]

Here's the deal. I have a 120 gal reef and the fish got velvet.

I ripped apart the whole tank and quarantined all the fish, however my six line wrasse hid somewhere in the LR and is now back in the DT.

I have been unable to catch it with a fish trap and whenever I go into the tank he disappears into the rock somewhere.

The other fish have all responded to the cupramine treatment and are recovering nicely. They have been in QT for a week.

The six line wrasse shows no visible signs or symptoms of the disease at all.

Even if I rip the tank apart again, there is no guarantee I will find the wrasse because he is hiding within the LR.

I am going to also try some really small hooks baited with salmon eggs.

My question....if I am unable to catch him and he is still symptom free after the 4 weeks of treatment, will it be safe to return the other fish to the tank?

I would appreciate any thoughts or advice.
Thanx
