A fish parasite, the isopod Cymothoa exigua, replacing the tongue of a Lithognathus. Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. [1]
The world's smallest fish depends on the measurement used. [1]Based on minimum standard length at maturity the main contenders are Paedocypris progenetica where females can reach it at 7.9 mm (0.31 in), [2] [3] [4] the stout infantfish (Schindleria brevipinguis) where females reach it at 7 mm (0.28 in) and males at 6.5 mm (0.26 in), [1] and Photocorynus spiniceps where males can reach it at 6. ...
The Hawaiian cleaner wrasse or golden cleaner wrasse (Labroides phthirophagus), is a species of wrasse (genus Labroides) found in the waters surrounding the Hawaiian Islands. The fish is endemic to Hawaii. These cleaner fish inhabit coral reefs, setting up a territory referred to as a cleaning station.
This type of polyandry was found throughout a variety of elasmobranch fish, or cartilaginous fish, such as sharks. [16] These sharks included lemon sharks, [17] sandbar sharks, [18] nurse sharks [19] and catsharks. [6] For convenience polyandry to occur, the costs of females resisting males must outweigh the costs of mating. [6]
These saprophytic organisms may then be predated upon by protozoa, rotifers and, in cleaner waters, Bryozoa which consume suspended organic particles including viruses and pathogenic bacteria. Clarity of the water may begin to improve as the protozoa are subsequently consumed by rotifers and cladocera . [ 4 ]

About 120 species are known to form such symbiotic relationships; members of the genera Amblyeleotris and Cryptocentrus, for example, cohabit in burrows with alpheid shrimps, while other species live as cleaner fish, e.g Elacatinus. They can be sequential hermaphrodites and numerous species are known to exhibit parental care. [1]
