tangs seem to like my cleaner shrimp, the maroons seem to like my neon goby i have both just because some fish do not like the shrimp, and the others the goby, my sailfin likes both, ive watched him let the cleaner shrimp clean the inside of his mouth was kinda funny, he was quivering but seemed to like it, hes also let the neon goby go into his gills, that was just disgusting
