c.dawg-I'm only relating my experience-not giving a definitive answer.Many of my experiences with fish and corals are very different from other members.I often see posts that give answers as though things can only be "this way" ,or to find out the answer was just just given by copying from another member or another message board as though the poster had personal experience.I always look for posts with known personal experience when I am considering adding a fish or coral to determine what I might expect and which of my tanks the addition will go.
My Geometric pygmy hawk lives in a cave with a blood shrimp(Lysmata debelius)and at night they are joined by a scarlet cleaner(Lysmata amboinensis),which is very different from what others have posted,but obviously not all of these fish will eat cleaner shrimp.They have lived peacefully this way since June 2005.
