Description of decorations: Very similar to the tree branches that appear in habitat videos. Sand with a grain structure of 1 mm or smaller, used in beige color, completed this composition. A good contrast with the sediment of dried leaves falling from the trees. Orinoco river underwater videos followed by the horizon line, the closest color was selected and used as backdrop.
装饰描述：与栖息地视频中出现的树枝非常相似。采用米色、颗粒结构为 1 毫米或更细的沙子，完成了这一构图。与树木落叶形成的沉积物形成良好对比。背景参照奥里诺科河水下视频中的地平线，选取最接近的颜色作为背景板。

INFORMATION ABOUT BIOTOPE
关于生物群落的信息

Description of the area surrounding the biotope: The source of the Orinoco river was discovered in 1951 by Venezuelan researchers in Sierra Parima, near the Brazilian border. 2140 km long, one of the longest rivers in South America. This rare river bifurcated, although it advances towards the north, instead of the Caribbean Sea, the South East swirls and flows into the Atlantic Ocean.
生物栖息地周边区域描述：奥里诺科河的源头于 1951 年由委内瑞拉研究人员在靠近巴西边境的帕里马山脉发现。该河全长 2140 公里，是南美洲最长的河流之一。这条罕见的河流发生分汊，尽管其主流向北推进，但东南支流却蜿蜒注入大西洋，而非加勒比海。

This region, which has a delta area of 41.000 km² and a very high variety of living, includes swamp areas. It is an indicator of the change in the water level in the region where the average annual rainfall is 2700 m3 and it is the explanatory of clear waters.
该地区拥有面积达 41,000 平方公里的三角洲，生物多样性极为丰富，并包含沼泽地带。此处年均降水量达 2700 立方米，水位变化显著，同时也是清澈水质的典型代表。

Description of the underwater landscape of the biotope: The imitated region is the low-flow Orinoco river in the state of Bolivar. The flora is very rich in the area with clean water. Since the parts where mechanical and organic deposits are abundant are imitated, dried terrestrial grasses and natural materials to collect sediments are used in the aquarium.
生物栖息地水下景观描述：模拟区域为玻利瓦尔州境内流速缓慢的奥里诺科河段。该区域水质清澈，植被极为丰富。由于模拟的是机械沉积物和有机沉积物丰富的河段，水族箱中使用了干燥的陆生草类及天然材料以收集沉积物。

The area, which does not have excessive debris and tree branches lying on the river floor, has large swimming areas. River water parameters have an average temperature of 5.2 – 6.5 pH, 25-30 ° C during the year.
该区域河底没有过多的碎屑和树枝，拥有广阔的游泳空间。河水参数全年平均为：pH 5.2–6.5，温度 25–30°C。

The highest temperature of the year reaches 30 ° C in September.
一年中的最高温度出现在九月，可达 30°C。

Description of the parameters of the habitat: Temperature 25-30°C, pH 5,2 – 6,5, hardness(dH) 2,80 – 5,60
栖息地参数描述：温度 25–30°C，pH 5.2–6.5，硬度 (dH) 2.80–5.60。

List of fishes and invertebrates occurring in the nature biotope: Apistogramma hongsloi, Biotodoma wavrini, Cichla orinocensis, Farlowella acus, Mikrogeophagus ramirezi, Corydoras concolor
自然生物群落中出现的鱼类和无脊椎动物名录：阿氏短鲷（Apistogramma hongsloi）、瓦氏双冠丽鱼（Biotodoma wavrini）、奥里诺科慈鲷（Cichla orinocensis）、针状远帆鲇（Farlowella acus）、拉氏微几何鲷（Mikrogeophagus ramirezi）、同色 Corydoras（Corydoras concolor）。

List of plants found in the nature biotope: Eleocharis Parvula, Salvinia natans, Riccia fluitans, Cabomba furcata, Bacopa monnieri
原生境中发现的植物列表：小荸荠（Eleocharis Parvula）、浮萍状槐叶蘋（Salvinia natans）、浮水地钱（Riccia fluitans）、叉叶狐尾藻（Cabomba furcata）、假马齿苋（Bacopa monnieri）

Threats to the ecology: Orinoco, which has the most powerful river systems in the world, is relatively robust compared to many other rivers. But the pink river dolphins that are unique here are under great threat. Their numbers are gradually decreasing. Unless measures are taken due to pollution, boat traffic, fishing and dams, this will pose a major threat.
生态面临的威胁：奥里诺科河拥有世界上最强大的水系之一，与许多其他河流相比相对稳健。但此地特有的粉红河豚正面临巨大威胁，其数量正逐渐减少。若不针对污染、船舶交通、捕捞及水坝建设等问题采取措施，将构成重大危机。
