As the title states, I have a 48x24x24 and I have recently added a Lubbock's fairy wrasse and my Starry Blenny has been chasing the wrasse back to it's hiding hole. Anyone have any idea why a Blenny would chase Wrasse?
Initial agression towards newly introduced fish is pretty common. I wouldnt worry too much about it unless it continues longer then a few days. And blennys are mean and do not like it when anything comes near their lounging area.
