One fish beats up another

[French Wright]

I have a bi-colored pseudochromis that is harassing a blenny, preventing him from working the sand over half of the aquarium. I moved the LR around last night to "re-set the playground", and had limited success. The blenny is new to the tank, maybe 4 days at this point. Anyy suggestions?

pseudochromis are known to pick on other fish...its just how they are but it could be since your blenny is new its just establishing the pecking order in your tank still...give it a bit and see if the pseudochromis calms down if not you may have to take it out...thats what i had to to because mine was killing my firefish...

I had a purple pseudo in my tank, I had to take him out,he was a real bas****! I added him as 1 of my 1st fish(my mistake), anyway I had to tear down my entire tank to catch him so I could get him out. It's way more peaceful now........
