The fish should be treated for a full 4 weeks if using hyposalinity and then a few additional weeks to monitor for any re-occurances or secondary infections. If using copper (which I do not recommend), the treatment period is typically 3 weeks and then you should allow the same two weeks after to monitor for re-occurances or secondary infections. So basically 5-6 weeks.
also is that too small fro a blenny, clown, and dwarf angel?
It's a bit cramped but it really depends on how big the angel is. Place an ample amount of PVC
pipe and elbows to give them plenty of places to hide and it should help. If you think it's going to be cramped, you might need to upgrade the QT
to a 20 gal
How do you sugest catching them?
With a net
Since you are removing all the fish you really do not need to be concerned with disrupting the tank. You should be able to pull out any LR
or other obstacles easily enough.
