It needs, obviously, of water filtered and oxygenated, very poor of nitrogenous substances and phosphates; they are advises to you you attend water changes with sifonatura of the bottom and regular added of Soccer, Strontium, oligoelements and bioelementi.
 
It goes nourished with plancton frozen-dry made to recover some minute in water, preferibilmente the same one of the Aquarius, or better, dept freeze, to spuzzare with an appropriate syringe in the pressed ones of the colony; if the much large colony of T. Geofroyi pu to be nourished also with pezzetti of polpa of cozza or brandelli of fish supports to you delicately on the tentacles before extinguishing the lights.
