I want to add a blue neon goby to my tank for the cleaning service, but I dont know how to intoduce it. My female clownfish is around 3-4 inches, and my majestic angle is around 3 inches. I think they could both eat it,

. Do they know the fish is a cleaner, and will leave it alone?? Mybe introduce it at night?? I put a cleaner shrimp, and two peperment shrimp in the tank yesterday, and my dottyback and female clown ate one of the pepperments!! But left the cleaner alone..... Would the same thing happen if I put a sand shifter goby in there?? Any info would be great,
Michael
