I have a starry Blenny, he has been awesome in my tank until recently. Now everything I put in the tank this guy murders within a couple of hours. I have a 45Gal with the Blenny, a goby, a clown and a royal gramma. The goby and royal both came after the blenny and zero aggression was shown towards either. Now it has been about 6 months since I added the royal and I tried adding a new fish, a McKoskers wrasse, the second the wrasse hit the water the blenny went nuts, and killed it in under and hour. Tried to get either one out and couldn't. Next I tried a midas blenny, almost an inch bigger than the blenny, again under 2 hours he was dead. This guy isnt just stressing these fish out, hes actively killing them. So before I get a fish trap and get the killer out, is there anything I can do to stop this guy or does he have to get taken out of the tank?? I want to add a couple more fish but this guy is making it impossible!!

The aggression and territorial behavior is unlikely to stop. You'll need to remove the blenny if you want to safely add more fish. A prolonged timeout in the sump or another tank might work, but there's always the possibility that the behavior will return when the blenny is reintroduced.

Unfortunately, removal is about the only thing you can do.
