Midas blenny/clown aggression

[Sarah1990]

I got two ocellaris clowns 2 weeks ago and they have settle in nicely seeming to prefer the front right corner.
Yesterday I added a midas blenny, watchman goby and a pistol shrimp. The blenny and goby have both decided to stay in the same area as the clowns and when the blenny comes out he/she and the female clown end up nipping at each other.
Is this normal or is there something I can do to maybe encourage the blenny to find another cave?
Also the shrimp and watchmen were together in acclamation but have ended up at different ends of the tank, is it likely they will find each other and pair or could I try to get them to each other?

All of that space and all 4 are in this corner haha

Just watch them that injury isn't occurring outside of a little nipping. Heirarchy wil be determined and hopefully all will settle down. The Blenny will move if he/she doesn't come out on top of the argument.

I have a Midas Blenny and a very aggressive female clown... The Blenny is the boss and they all get along great.
