Fish group dynamics

[megadon]

I put a Tomato clown in my tank about a week ago, now it seems my Yellow Wrasse is very shy. He used to swiw around with the dwarf Angle, no it seems the dwarf Angel is buddies with the Tomato and now the Yellow Wrasse hides all the time, coming out a bit for food. Is this just the way it goes or will he make a social recovery?

Tomato clown are very aggresive! IT could be that the clown is being a bully!

The Tomato doesn't seem aggressive, the Angel swims around with it now instead of with the Wrasse. I haven't seen it chasing the Wrasse. I hope he comes back in view, he was really cool swimming all through the rock and around the tank. It seems like my tank and set up is made for just 2 fish, 3 upsets the balance.
