Беспозвоночные которые не живут в банках долго.

[Stanislav 3]

И наверняка погибают через некоторе время. Предлагаю выкладывать здесь инфу по видам которые не могут жить в неволе по определённым причинам, и указывать эти причины. таких видов увы много привозится и продается: голожаберники, flamescallops, большинство ципрей, морские лилии, некоторые кораллы.

 

Начать можно с морских лилий.

 

"They are also among the most difficult to keep alive in captivity for anything over a few weeks. Unlike some echinoderms, crinoids appear to be relatively hardy with regard to water conditions. This is likely a result of their reduced body cavity sizes compared to all other echinoderms, so the potential for damages due to changes in salinity is minimized. Unfortunately, this relative hardiness does nothing to confer a survival advantage in aquaria.

The sea lilies, or stalked crinoids, are often very abundant at depths exceeding about 300m (1000 ft). Free-living crinoids are very abundant on Indo-Pacific reefs, and are present but less obvious on Caribbean ones (Fell 1966; Messing 1997). They are all "passive" suspension-feeding animals, which means they don't generate the water currents that bring food to them (Leonard 1989). This means that not only is the type of food important in their husbandry, but also that they likely need water flow that has specific characteristics. They are not animals that are normally found in regions of turbulent flow or surge, and it is unlikely that they could ever persist in a reef aquarium whose current flow was turbulent and generated by point source generators such as power heads. Although it has not been investigated, they probably need laminar flow to be able to feed.

Additionally, their diets are unusual in that they often appear to contain large amounts of the reproductive materials of other invertebrates (Rutman and Fishelson 1969; West 1978; Meyer 1979, 1982a, 1982b; La Touche and West 1980; Smith et al. 1981; Holland et al. 1991). It appears that many crinoids may engage in what is termed glutinous feeding, essentially "pigging out" during mass reproductive events such as the synchronous spawning of reef corals. Presumably, they get the majority of their food energy during such times, but they may still need to regularly feed on other plankton. Other than the reproductive products of other invertebrates, they appear to eat ciliated protozoans, and small crustacean zooplankton.

Although there are a few scattered reports of one or two individuals persisting in aquaria, in most cases the crinoids imported for the reef hobby die within a short period. They typically die by slowly sloughing off the distal ends of their arms until all that is left is the body, which then dies. This pattern is consistent with what happens to other echinoderms during starvation, and it is likely that effectively all of the crinoids imported for the aquarium hobby die of starvation within a few weeks of being placed in a reef tank. Until such time as aquarists have access to a constant supply of eggs, embryos, or invertebrate larvae of several types, the husbandry of crinoids should not be attempted."

Текст простой без заморочек, но если надо сазу переведу, а английский тут похоже тут все знают.

Зеленая лилия у меня прожила больше полутора года, и еще бы жила , если бы ее не придавило камнем :cry: , правда ее никогда не было видно, так как она жила за камнями.

Да интересно, в инете куда ни глянь не протягивают и несколькоих месяцев. Лишь из редка отмечаются случаи выживания более года. Видимо у вас хорошие условия дляее пропитания.

Очень интересно. У меня есть некая животинка, похожая на ту, что на фото. Очень маленькая, фотографированию никак не поддается. Как правило, появляется из камня ночью. Гдето то 7-10 щупалец, таких же, с зубчиками(ресничками?), как на фото, пестрые. Двигаются из стороны в сторону. Все думал - что бы это могло быть... Неужели лилия нелегалом прибыла ? :shock:

Прошло уже прелично времени, может у кого-нибудь есть удачный опыт содержания лилии?
