Enormous Bivalve clam, pertaining to the order of the Veneroidi, family of the Tridacnidi, present in the western Pacific ocean, in Malaysia, Micronesia and Indonesia, Taiwan islands, Marshall and Fiji; the classification of several the somewhat difficult species perche counts only the shape and the dimensions of the valve, the color of the extremely variable cape from individual to ininfluente individual and therefore.

From the shape relatively to goblet, much convex one, with the valve sturdy, long until to 1,5 meters, covered from wide longitudinal costolature, used in order to berth the cape when it comes estroflesso; to the center of the very visible cape the blowing, prominente hole of the sifone regarding the woven one around, to the extreme side instead little striking the aspiring hole of the sifone.
The cape of the T.Gigas appears always extremely colored for the presence to its inside of a great number of alghe Zooxantelle, which lives in simbiosi with the animal; in order to favor the presence of the Zooxantelle the cape estroflette to outside of the valve and moreover, possesses of the particular organs to disc of a valve shape in order to concentrate the solar light.

However the T. Gigas 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 the greater 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 one moderated current that removes the refusal products secreti.
Relatively little demanding as far as the chemical values of the water that must be filtered, be only very aereata and it deprives of nitrites and nitrates.
They are, however, always advisable changes of the water with sifonature of the bottom and regular oligoelement additions, balanced bioelementi and soccer.

Reached nearly the extinction because of the indiscriminate hunting due to the prelibatezza of the meats hour, thanks to the acquacoltura, practiced mainly in Micronesia, in the island of Malakal, to of l of Koror, where has center the Micronesia Mariculture Demonstration Center, an engaged laboratory of marine search in such plans trades them; far from such risk; they remain however the limitations of 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.
