Need help getting rid of Mantis shrip. He is attacking my sail fin blenny. My blenny has been sitting on the bottom of the tank not very active like he is hurt. I thought at one time he was dead. Today I saw the mantis shrimp attack him and I responded in defence but could not get him. I suppect that the shrimp is what killed my sea cucumber last week. Any sugestions.
