I’ve had my Naokoae take out a Peppermint in the past however nobody dares to touch a Cleaner (specifically Lysmata amboinensis).
Lysmata amboinebsis and Lysmata grabhami both have very important roles in a reef. Even though they’re from two totally separate areas, they both still hold the same roles. This is to clean dead scales, parasites and other organic matter off of the fish. Due to this role, many fish ignore the shrimp and instead use them to clean themselves.
A Cirrhilabrus species is much less likely to go for a Shrimp (even a non-cleaner shrimp). This is due to their wild diet being primarily planktonic. They feed on the plankton and other small pelagic crustaceans that are in the water column. In captivity, they tend to hold a similar diet however we can feed them with other things as well. I know my 4 Paracheilinus/Cirrhilabrus go crazy with pods that are in the water column then ignore them once they go down into the rocks and sandbed.
So, while it isn’t impossible for a Cirrhilabrus or Paracheilinus species to go for a Shrimp, it is incredibly uncommon and not as heard of unlike a larger Halichoeres species killing a small (<1”) shrimp.
