For a number of good reasons there are a many varieties f livestock that are unsuitable for captivity. Specialized diets, growing to too large a size, easy susceptibility to disease, poor adjustment to aquarium conditions, being too dangerous, too rare, or performing a needed function in the wild among other traits preclude certain species being attractive to aquarists.

Unfortunately this list includes specimens that are regularly offered to the hobby. Why? The answer not surprisingly is someone will buy them. I would like to believe that mainstream aquarists are an informed, conscientious lot dealing from a position of knowledge with intelligent, honest dealers, wholesalers, transhippers... all the way back to the collectors and breeders. Alas, I must be dreaming. How much do any of us know re what we do? Is it enough to have the means and desire to "buy" what you want?

This is the genus of obligate Cleaner Wrasses most celebrated for establishing stations in the wild that are frequented by "local" reef fishes and pelagics for removing parasites and necrotic tissue. Perhaps shocking to most aquarists, all the Labroides rate a dismal (3) in survivability, even the ubiquitously offered common or Blue Cleaner Wrasse, Labroides dimidiatus. None of the Labroides should be removed, not only for the fact that almost all perish within a few weeks of wild capture, but for the valuable role they play as cleaners.
