Beautifulst Echinoderma, class of Asteroids, pertaining to the order of the Valvatida, family of the Ophidiasteridi, present in the Pacific ocean and the Indian ocean.
 
Extremely characteristic for its shape to star with five arms coloration introduces one much particular one: on the body of color red brunastro, similar to the F. Elegans large tubercoli enclosed in a dark reticulum are present, of a black one verdastro; the tips of the arms are, usually, much dark, nearly black.
 
The disc centers them, devout massive of the congeneri, has the little obvious pori of the system acquicolo.

 
In nature alive carefullied lay down on the full of rocks bottom, or embedded between the madrepore, however always in places little it illuminates or decidedly oxen to you; extremely lively one moves muovendo incessantly the ambulacrali small foot-stalks continually presents in the inferior part of the arms; such small foot-stalks beyond to the deambulatoria function acquit also the function of collection of the food.
 
In nature the F. Elegans nutre in fact of alimentary microparticles is of animal origin that vegetable, alghe, sponges, rotiferi, small polipi as soon as insediati, that it collects incessantly from the substrate on which walks.

Much difficult one to raise in Aquarius, is for its particular feeding, is for the sensibilit to the chemical-physical characteristics of the atmosphere.
 
E' therefore necessary to somministrare frequently smallest quantit mangime for microplancton or appropriate animals microfagi, frozen-dry or dept freeze, in order to avoid that this splendid Echinoderma dies quickly of starvation.

 
Sensitive and demanding as far as the chemical values of the water that must be a lot very filtered, aereata and absolutely lacking in nitrites and nitrates.
 
They are advisable regular and abundant changes of the water with sifonature of the bottom and regular oligoelement additions and balanced bioelementi.
 
E' important moreover to cure very the breaking in in the bathtub, the F. It indicates, like all the others pertaining to the class of Asteroids, must be immessa in the new Aquarius after a longest acclimatization, drop to drop, and, above all, in position turned upside down, way from being able to expel from the boccale opening eventual air bubbles that could have ingested during the transport.
 
For all these reasons would have to be raised also in the Aquarius of invertebrates of the acquariofilo principiante purch equipped of much patience in feeding this colorful Echinoderma much but delicate one.
