Impulse decision? Maybe. Thoughts?

I don't know about the shrimp but I do know that even though the neon is one of the more passive dottybacks inch for inch these fish are probably the most beligerant fish there are.
I have a royal dottyback in my 230g and he does not hesitate to take on any fish in the tank including a large Hippo Tang, yellow tang, Maroon Clown etc. etc. I also cannot keep any small fish in this tank as if he does not manage to kill them outright he has figured out how to chase them directly into my carpet anemone - I have watched him do this to 3 gobies. The only small fish he leaves alone are the 2 mandarins in there.
