Ceratophyllum

Ceratophylls can be found all over the world, but only one species is common in aquariums.

Ceratophyllum demersum

The water sprite is found in Europe and Central America, though this temperate water plant can adjust to tropical aquariums. It is well suited to tanks with goldfish or garden ponds, where it can sometimes grow in profusion. It is easy to cultivate, although its stem breaks easily. It does not have any true roots and finds it difficult to establish itself in the substrate; it therefore has to be "wedged in" by rocks or branches, or float on the surface. It is easy to take cuttings from the main stem, or from side shoots. It is relatively indifferent to the hardness and pH of the water, but it does require strong lighting. Size: 30-40 cm.

Серия романов из 14 книг о похождениях "агента 007" Джеймса Бонда - характерное явление "массовой культуры": мелодраматические положения и экзотический антураж сочетаются с проповедью сильной личности, действующей в рамках жестко поставленной цели, часто вопреки общепринятой морали.
