My Longnose Hawkfish in my 90 gallon reef leaves my Peppermint Shrimp alone. He even lets my TINY Scarlet Skunk Cleaner Shrimp (less than 1 inch) clean him. Based on my readings, I have concluded I have a mentally insane hawkfish
So I would go with no longnose.
I would recommed the Green or Citrinis Clown Goby. I am getting a green one for my future 29 Biocube
