New fish being picked on.

[BuschWacker]

I have a 46g bowfront. I've got a 6 line wrasse, fire fish, anthias, and a 3 stripe damsel. They all get along very well and are very well behaved. Yesterday We purchased a strawberry dottyback, and a canary blenny. Now the wrasse and damsel are picking on the 2 new fish. Darting and nipping at them. Is this going to be an ongoing problem? Or are they eventually going to leave them alone. I bought a floating breeder tank today as well to try and separate them. Do I separate the 2 new fish for a few days or stick the misbehaving fish in therefor a few days?
