Blenny aggression

[DrufusReef]

So I have a Bi-color blenny along with 3x reef Chromis and a Yellow Foxface which all seem to get along great together in a 100g display. About two months ago I added a Solar Fairy Wrasse., which looked great for about 3 weeks and then started hiding more and more, and eating less and less until he died. I then added a Diamond Watchman Goby, and after a day the Blenny would not let him out of his cave. I tried to separate them by putting the blenny in my sump for a week, but when he came back he was just as aggressive. The goby was already to scared to come out and eat so he died too. I know the Blenny killed the Goby by not letting him eat, but I'm wondering if there might have been some aggression with the wrasse that I just didn't catch? Before I completely remove the blenny from the tank (to give back to the LFS) are there other fish I could add (tang, anthias, clowns. etc.) that might disperse the aggression so I can add more fish with similar body types to the blenny? I really want a fairy wrasse and a sand sifting goby in the tank

You are probably best to remove the blenny. I have a Midas Blenny that has been a model citizen for the past couple of years...until it became the devil and is now bullying my Diamond Goby relentlessly. I have already had to remove the goby and fatten him up in a quarantine tank for a month due to the Blenny forcing him into a cave constantly. He is now back in the tank with the Blenny...I just make sure I am directly feeding him with a turkey baster daily to keep him plump. He no longer works on the sand bed out of fear of the Blenny.

The blenny doesn't bother any of my other fish...Clown or Leopard wrasse, but both of those fish also have aggression tendancies that keep everyone else in check.
