Volume: 180 L  容积：180 升
Dimensions: 100x40x45 cm  尺寸：100×40×45 厘米

List of fishes: Sewellia lineolata
鱼类名录：线纹腹吸鳅（Sewellia lineolata）
List of plants: Evolvulus sp., Potos sp.
植物名录：旋花属（Evolvulus sp.）、麒麟尾属（Potos sp.）
Description of decorations: The bottom consists of river sand 1-10mm, stones of various sizes and driftwood are used
装饰描述：底部由 1-10 毫米的河沙组成，并使用了各种尺寸的石头和沉木。
Description of equipment: Filtration consists of pumping head JKA-IP203 and biomolitan cube of size 20x10x10 cm, light is used fluorescent Atman AT 130B and 2x 40W fluorescent tubes
设备描述：过滤系统由 JKA-IP203 泵头和尺寸为 20x10x10 厘米的生物过滤立方体组成；照明采用阿特曼（Atman）AT 130B 荧光灯及两根 40 瓦荧光灯管。

Water parameters: pH 6.5, 24 ° C temperature, PPM 130, TDS 260uS
水质参数：pH 6.5，温度 24°C，PPM 130，TDS 260 µS。
Additional info: The aquarium is prospering, it just does not manage to grow biofilm on the stones. Despite this, sewellia regularly grows and thrives. I would like to point out that Evolveus does not primarily belong to the surface, but occurs on the banks and often extends into the water where its shoots are pulled by the current.
补充信息：水族箱状态良好，只是石头上尚未形成生物膜。尽管如此，塞韦利亚鱼（Sewellia）仍定期生长并茁壮成长。需要指出的是，演化草（Evolveus）并非主要属于水面植物，而是生长在河岸，并常延伸至水中，其枝条会被水流牵引。

INFORMATION ABOUT BIOTOPE
关于生物群落的信息

Description of the area surrounding the biotope: This stream is located west of the city of Hue in Hương Hà, H Trng Trà, Thua Thien-Hue, Vietnam. It flows through a hilly, mountainous landscape covered with forests. It is formed by the confluence of several small streams about 6 km west of the mouth to the Huong River.
生境周边区域描述：该溪流位于越南承天顺化省香茶县香河社，处于顺化市以西。它流经覆盖着森林的丘陵山地景观，由数条小溪在汇入香江口以西约 6 公里处汇合而成。

The banks are lined with dense forest with lots of grass, ferns, shrubs and mature trees. There are representatives of the genera Argyreia, Evolvus, Ipomoea, Merremia, Porana, Dipterocarpaceae, Podocarpus and many other species of leafy and coniferous trees. Nearby is a relatively large mining pit for mineral resources.
河岸两侧密布着森林，生长着大量草本植物、蕨类、灌木和成熟乔木。其中包括银背藤属（Argyreia）、旋花属（Evolvulus）、番薯属（Ipomoea）、鱼黄草属（Merremia）、鸡矢藤属（Porana）、龙脑香科（Dipterocarpaceae）、罗汉松属（Podocarpus）以及众多其他阔叶和针叶树种。附近有一处相对较大的矿产资源采矿坑。

Description of the underwater landscape of the biotope: Sewellies occur in shallow very fast parts of the stream with markedly oxygenated water. The water is extremely pure, clear without color or with only a slight brown color. The base is mostly rocky, consisting of smooth stones, in some places sand. In the water there are limited fallen leaves and driftwood. Aquatic plants do not occur.
生境水下景观描述：塞韦利鱼（Sewellies）栖息于溪流中水浅、流速极快且溶氧显著较高的河段。水质极为纯净清澈，无色或仅略带褐色。河床主要为岩石底质，由光滑的石块构成，局部区域分布有沙砾。水中落叶和沉木数量有限，无水生植物分布。

Description of the parameters of the habitat: Ph can vary depending on the season and the amount of rainfall, ranging from 6-7.5. This also applies to water hardness and may range from 18-180 PPM. The temperature ranges from 20-24 ° C
栖息地参数描述：pH 值会随季节和降雨量的变化而波动，范围在 6-7.5 之间。水的硬度也是如此，可能在 18-180 PPM 之间。温度范围为 20-24°C。

List of fishes and invertebrates occurring in the nature biotope: Sewellia lineolata, Annamia normani, Balitora sp., Schistura sp., Glyptothorax sp., Anguilla marmorata a Rhinogobius sp.
自然生物群落中出现的鱼类和无脊椎动物名录：线纹腹吸鳅（Sewellia lineolata）、安南小鲃（Annamia normani）、平鳍鳅属（Balitora sp.）、南鳅属（Schistura sp.）、爬岩鳅属（Glyptothorax sp.）、花鳗鲡（Anguilla marmorata）以及吻虾虎鱼属（Rhinogobius sp.）。

List of plants found in the nature biotope: They do not occur
自然生物群落中发现的植物名录：无分布。

Threats to the ecology: There is no direct threat to the biotope in this area, even though there is a stone quarry nearby and it is possible that it will grow over time and that there is a risk of further deforestation of the landscape. And since the typical habitat of Sewellia is a rocky bedrock, there is a certain risk.
生态威胁：该区域的生物群落目前没有直接威胁，尽管附近有一处采石场，其规模可能随时间扩大，且景观存在进一步森林砍伐的风险。由于线纹腹吸鳅的典型栖息地为岩石河床，因此存在一定的风险。
