Colonial Antozoo small of the order of the Alcionacei, coming from mostly from the Pacific ocean and that Indian.
 
Completely lacking in a skeletal support, it has a tubular shape, a lot lengthened, with one small crown of tentacles; shape large ramificate colonies, to large shape way hand, having carnosa consistency, of color cream or gray.

 
Sessile, the fixed colony saldamente to the substrate by means of an adhesive disc, to times similar to the roots of a tree; several the individuals are in great part dipped in the common mesoglea leaving estroflessa only the part finish them, equipped of one crown of small little urticanti tentacles.
 
In danger case the single ones polipi expel the water and they are withdrawn to the inside of the mesoglea, having made to assume to the colony a curious aspect.

Much sturdy one, for being an invertebrate, a lot adapted to the Aquarius of barrier in cohabitation with other invertebrates and small fish or average largeness, preferibimente Amphiprion, Acanturidi, Pomacentridi, Centropige.
 
It prefers to be arranged in a light water current, sufficente to move the part sweetly to tentacolare of the individuals, in such way that contributions the nutriment to the colony and remove the products of refusal secreti from the individuals, but much fort not to annoy and to make ritrarre the small polipi; also preferibile one zone with one strongly lighting system, best if obtained with linear fluorescent lamps or lamps HQI.

 
Nutre above all of the products of the Zooxantelle simbionti.
 
It does not have particular requirements, regarding the other invertebrates, as far as the chemical values and physical of the water that must very be only filtered, oxygenated, it deprives of nitrites.
 
It suffers moreover for the presence from nitrates and phosphates, in the which case the colony appears found it hard, little inclined to estroflettere the single individuals completely; they are therefore advisable frequent and abundant changes of the water with sifonatura of the bottom nonch regular oligoelement additions and bioelementi.

 
E' important to observe that the foot turns out integral and not torn and that not present hurt due to a little careful transport.
 
For all these reasons would not have to never lack in the Aquarius invertebrates the principiante to its first experiences, but also in that one of devout an expert acquariofilo.
