水质参数：温度 17-22°C，pH 值 7.5，ppm 160。
Additional info: Water changes once a week 30%. In cold water aquariums, additional aeration of water is more important than low temperature. In cold water there is more oxygen, if we can not lower the temperature, we must provide more oxygen. (Aquael OXYPRO 150.)
附加信息：每周换水 30%。在冷水鱼缸中，增加水中的氧气比保持低温更为重要。冷水中的氧气含量更高，如果无法降低温度，就必须提供更多氧气。（Aquael OXYPRO 150。）
INFORMATION ABOUT BIOTOPE
关于生物栖息地的信息
Description of the area surrounding the biotope: A small stream originating in forests to the southwest of the city of Bełżyce. These are mixed forests, the most common tree species are: Quercus, Carpinus betulus, Pinus silvestris, Alnus glutinosa. The biotope is located in a temperate cold climate. The driest month is January. There is a rainfall of 24 mm at this time. The greatest precipitation appears in July, with an average of 77 mm. July is the hottest month with the average temperature of 18.5 ° C. The lowest average temperature in the year occurs in the month of January and is about -5.6 ° C.
生物栖息地周围地区的描述：一条发源于比尔斯克市西南部森林的小溪。这些是混合森林，最常见的树种有：橡树、白榆、欧洲赤松、欧洲柳。生物栖息地位于温带冷气候区。最干燥的月份是一月。此时降雨量为 24 毫米。七月降雨量最大，平均为 77 毫米。七月是最热的月份，平均气温为 18.5°C。全年最低平均气温出现在一月，约为-5.6°C。
Description of the underwater landscape of the biotope: The stream’s sources flow from a small hill. The silty bottom is overgrown with algae. After about 20 meters, the bottom is covered with limestone and sand, the banks are overgrown with roots, mosses and dead wood.
生物栖息地水下景观的描述：溪流的源头流自一个小山坡。淤泥底床上长满了藻类。大约 20 米后，底部覆盖着石灰石和沙子，河岸长满了根系、苔藓和枯木。
Description of the parameters of the habitat: Transparent water, pH 7,57, ppm 179, temp. in summer 14-15 ° C
栖息地参数的描述：透明的水，pH 值 7.57，ppm 值 179，夏季温度 14-15°C
List of fishes and invertebrates occurring in the nature biotope: Barbatula barbatula, Gasterosteus aculeatus, Gobio gobio, Gammarus pulex, Orconectes limosus (Invasive species)
鱼类和无脊椎动物清单，存在于自然生物群落中：Barbatula barbatula、Gasterosteus aculeatus、Gobio gobio、Gammarus pulex、Orconectes limosus（入侵物种）
List of plants found in the nature biotope: Algae
自然生物群落中发现的植物清单：藻类
Threats to the ecology: Due to global warming, the stream dries up. In the summer about 200m from the sources the depth of water was 1cm !!! Despite the harsh conditions, there are fish there, probably their last years in this biotope. Also people who ride off-road vehicles contribute to the destruction of the biotope. One of the local small miracles of nature dies.
生态威胁：由于全球变暖，溪流干涸。在夏季，距离源头约 200 米处，水深仅为 1 厘米！！！尽管条件严酷，但仍有鱼类存在，可能这是它们在这个生物群落中的最后几年。此外，越野车辆骑行者也对生物群落的破坏做出了贡献。自然界的一个小奇迹正在消逝。
