I agree it is natural instinct to go to Cleaner Shrimp. But I will revise my statement to say that fish will go to Cleaner Shrimp when something is irritating them and not exclusively Parasites. I have 2 mature Cleaner Shrimps in my DT and have never once seen my Fish posture for cleaning even when the Shimp's attempt to.I have 26 tangs and two cleaner shrimp and they go up to shrimp always as shrimp set up cleaning station. Havent had disease in many years. Its a natural instinct
