Bivalve clam, pertaining to the order of the Veneroidi, family of the Tridacnidi, present in the oceans Indiano and Pacific, Red Mar, Vietnam and Malaysia; the acknowledgment and the several classification of the somewhat difficult species perche count only the shape and the dimensions of the valve, and only to times some morphologic particular, the color of the extremely variable cape from individual to absolutely useless individual and therefore to such scope.
From the shape roughly triangular, with the valve sturdy, much convex, long until 45 cm., covered from tightened costolature, little obvious; used in order to berth the cape when it comes estroflesso; to the center of the cape, small but a lot lengthened, the sifone blowing, little obvious, instead, the sifone aspiring.
The cape of the T: Crocea appears always extremely colored for the presence of a great number of alghe Zooxantelle that lives in simbiosi with the animal; in order to favor the presence of the Zooxantelle the T. Crocea estroflette the cape little to the difuori of the valve and possesses moreover of the particular organs to disc of a valve shape in order to concentrate the solar light.
However the T. Crocea to draw greater giovamento from the simbiosi in how much very many alghe is veicolate in the visceral zone and fagocitate and assimilated here; this fact to allowed to the animal, originally a filtratore, to draw one good part of its maintenance from the simbiosi with the alghe.
In nature alive embedded between cliffs or the madrepore, in Aquarius it prefers to be arranged on a limestone support, far away from the sand, in one extremely illuminated position, preferibilmente with linear fluorescent lamps with the temperature light 10,000 color K. and beyond or with lamps HQI; in a light current that removes the refusal products secreti.
Delicate E' much and demanding one as far as the chemical values of the water that must very be filtered, be aereata and deprive absolutely of nitrites and nitrates.
Frequent changes of the water with sifonature of the bottom and regular oligoelement additions, balanced bioelementi nonch of soccer are advisable, in quantit maintaining of the concentration to 450/500 ppm.
To the contrary of the other Tridacne, it seems that regular, small somministrazioni of plancton, frozen-dry or dept freeze, are necessary to the maintenance of the T. Crocea; this probably which had fact to minor a efficenza of alghe the Zooxantelle selected during the evolution from the T. Crocea regarding the other Tridacne, in fact transplanting in exemplary of T. Juvenile Crocea, Zooxantelle taken from one T. Gigas has been enormously increases the development to you and the survival of the individuals deals to you; ( study of the Dott.sa S. Suzanne Mingoa-Licuanan ).
Also being less searched than others for alimentary reasons, they remain the limitations in the peach and the export dictated from regulations C.I.T.E.S.
For all these reasons would have to only figure in the Aquarius of invertebrates of the acquariofilo expert; equipped of patience and means adapted to the maintenance of this splendid marine invertebrate.
