I keep a harem of 4 grammas along with a swissguard basslet in my 95 gallon...
there is no aggression between any of the grammas and the swissguard.
they are far from conspecific and most of these types of basslets are deep water species so they are usually in the dark corner of aquariums or hiding under overhangs/caves while the grammas generally stay out in the water column unless nesting.
If this is regarding your 180, these fish will likely ignore each other.
