Notropis chrosomus

Notropis chrosomus, может кто знает о содержании и разведении этой рыбки?

[Yan]

В нашем климате держать холодноводных рыб - занятие неблагодарное. Поэтому сомневаюсь, что у кого-то есть опыт их содержания.

Вот что написано про их условия обитания и разведения в "Biographies of Southeastern Freshwater Fishes:":

An aptly named minnow that is native to the upland streams of the Mobile River drainage, the rainbow shiner occurs in small to medium size creeks. This species is one of the many nest associates of chubs (relatively large minnows that build stone nests in the spring as spawning beds). Nest associates spawn over the nest of chubs and derive advantage from the aggressive male chub guarding against predators such as sunfish and bass. Thus, the eggs of the nest associate minnows also receive protection. For the fish watcher, observing spawning over chub nests is one of the rites of spring, yet has probably been observed less than some of our rarest birds. However, the chub nests are not difficult to observe; they are usually constructed at the head or the tail of riffles where the water surface rippling has ceased. Nest-guarding chubs are wary. However, a careful observer, using binoculars or a stealthy approach by snorkeling, may witness dozens–even hundreds—of brilliantly colored minnows engage in frenzied bouts of combat and spawning. The scene is mesmerizing, even to the most jaded biologist.

Ян, большое спасибо.
Сейчас сидят при 27гр.С.
Notropis chrosomus вроде 2 вариации, синего оркаса которые хорошо себя чуствуют при 18-24гр.С и красного окраса которые могут жить при 22-28гр.С, но вроде нерестятся в нижних пределах этих температур.
