According the fish store (who i also trust, because they are a well known & respected store in my country) a Amblygobius Linki is semi-aggresive & not always peacefull.I’m not sure what you mean - do you have a Link’s goby? They are peaceful, I don’t see that as being a problem.
It's a rare phenomenon but it could happen that they become aggressive towards a wrasse because they are in same living area. They could also become aggressive towards their own species.
My fish store now suggests a different species of wrasse that should be a better combo with the linki (when the time is right).
