Fish know how to clean

Hygienic fish with the scientific name Labroides dimidiatus, has a very strange relationship with other fish. Its bright color attracts big fish that want to be itchy. Fish Labroides dimidiatus have the ability to clean up parasitic plants and animals, which cause discomfort to other fish.

Everything goes very delicately: Big fish, fierce fish when approaching are careful to avoid making them panic and show "sincerity" is to be cleaned clean body.

While the big fish slept dimly, the tiny "cleaning fish" cleverly swam around, snapping all over the big fish body to eat "lice" and other parasites.

Fish Labroides dimidiatus even swim into the deep mouth of grouper to clean teeth. When the mouth is clean, big fish also open the gills to allow Labroides dimidiatus to get into the gills.

Sometimes the fish that wants to clean must wait for the turn to be cleaned. Both sides are beneficial: big fish are clean without any cost, and fish can clean and fill the stomach.

In reefs, where fish cleaning for some reason does not live there, the health of large fish is significantly reduced because of parasitic diseases.

Cleaned fish also have "market" and know how to protect "market share" - they occupy "customers" from other fish of the same species.

Another special feature of this type of fish is: If there is a scarcity of fish or females in a community, some will change themselves. Eggs are laid in the nest area and guarded by both the parent and the fish. When the eggs hatch, the fry drift between the rocks and eat the plankton until they are large enough to become "parasitic killers".

During the day, looking at fish Labroides dimidiatus is iridescent blue and a large black band runs along the length of the body from the lips to the tail. At night, the fish are very intelligent, know how to hide among the rocks and even know how to take the seaweed around them to safely hide.

Fish Labroides dimidiatus distributed throughout the Indian-Pacific region but excluding Hawaii.
