List of fishes: Paracheirodon axelrodi, Taeniacara candidi
鱼类名录：宝莲灯鱼（Paracheirodon axelrodi）、卡氏坦尼亚卡拉鱼（Taeniacara candidi）
Description of Decorations and Substrate: The substrate of the aquarium consists of pond peat bloks, a layer off 8 to 10 cm thick. This is very loose and fish can swim inside the substrate to hide or lay eggs. Two big trunks of driftwood to replicate the tree trunks of the Ficus trees. Braches and twigs I collected from oak trees. Guave leafes are used for the leaf litter layer because they look most like the leafs in the habitat. I only used one type of leaves because almost the entire area consists of Ficus trees.
装饰与底床描述：水族箱底床由泥炭块构成，厚度为 8 至 10 厘米。底床质地非常疏松，鱼儿可潜入其中躲藏或产卵。两根大型沉木用于模拟栖息地中的榕树树干。树枝与小枝采集自橡树。落叶层选用番石榴叶，因其形态最接近原生环境中的叶片。仅使用单一树种叶片，是因为该区域几乎完全由榕树组成。
Description of Equipment: Eheim external pump 2213 with a pump flow of 440l/h. I used a spray bar with more and bigger holes, so the flow rate is lower. Sera siporax and sponge filters.
设备描述：伊罕（Eheim）外置过滤器 2213 型，水泵流量为 440 升/小时。我采用了孔径更多且更大的喷淋管，以降低水流速度。过滤介质包括西拉（Sera）siporax 生物滤材与海绵过滤器。

Additional Info: Feeding only once or twice a week. I only added 9 Paracheirodon axelrodi, after a couple months I had 17 of them. Later, I added the 5 Taeniacara candidi and they hunted down every new born after that.
补充信息：每周仅喂食一到两次。我最初只放入了 9 条宝莲灯鱼（Paracheirodon axelrodi），几个月后数量增至 17 条。后来，我又引入了 5 条白点短鲷（Taeniacara candidi），此后它们捕食了所有新生的幼鱼。
The water in the aquarium is changed every 2 weeks in the amount of 10%.
水族箱中的水每两周更换一次，每次更换量为 10%。
I always add water of approximately the same temperature.
我总是添加温度大致相同的水。
Description of the Area Surrounding the Biotope: The igarapé Prosperitate is a tributary of the lower Rio Preto, a northern affluent of the Rio Negro, Brazil. The igarapé Prosperitate is a typical example of the countless small rain forest creeks of the Rio Negro region. The igarapé is located 12,5 km north-west off its junction with the Rio Negro. The actual stream bed is flanked by broad belts of flood plains, and virtually the entire course is fully shaded by the surrounding vegetation, chiefly Ficus trees. Only the mouth, where during low water the final 30 meters of the forest stream broaden to form a lagoon some 5 meters in width, is exposed to sunlight. Upstream from its broad mouth, the creek splits into two branches. One falls dry during low water, only flowing during periods of normal or high water levels. The other branch maintains a width of 1.5 meters and a depth of 20 to 30 centimeters. The forest encompassing the igarapé Prosperitate consisted of various Ficus trees that measured about 8 meters in height. At the peak of the water height they are submerged up to their crowns, up to about six meters.
生物群落周边环境描述：伊加拉佩·普罗塞里达特（igarapé Prosperitate）是巴西内格罗河（Rio Negro）北部支流下普雷托河（Rio Preto）的一条支流。伊加拉佩·普罗塞里达特是内格罗河流域无数小型雨林溪流的典型代表。该溪流位于其汇入内格罗河处西北方向 12.5 公里处。实际河床两侧分布着宽阔的洪泛带，几乎整个河道都被周边植被完全遮蔽，主要为榕树（Ficus）。唯有河口处在低水位时暴露于阳光之下，此时森林溪流最后 30 米展宽形成一个约 5 米宽的潟湖。在宽阔河口的上游，溪流分叉为两条支流。其中一条在低水位时干涸，仅在正常或高水位期间才有水流；另一条则保持 1.5 米的宽度和 20 至 30 厘米的深度。环绕伊加拉佩·普罗塞里达特的森林由多种榕树组成，树高约 8 米。在水位最高时，这些树木会被淹没至树冠，水深可达约六米。
Description of the Underwater Landscape of the Biotope: During this period of low water the igarapé mouth measured a maximum depth of 1.2 meters, with no more than 40 cm of water above the layer of leaf litter. All sections of the stream have a substrate of leaf litter several decimeters thick. The upper third of the leaf litter is relatively loose and interspersed with a multitude of branches. The entire watercourse and adjacent areas were scattered with numerous tree stumps.
生物群落水下景观描述：在枯水期，伊加拉佩河河口处的最大水深为 1.2 米，落叶层上方的水深不超过 40 厘米。溪流各段的底质均为厚达数分米的落叶层。落叶层的上三分之一较为疏松，其间散布着大量树枝。整个河道及邻近区域散落着众多树桩。
I replicated the shoreline of the mouth of the igarapé Prosperitate. There are tree trunks submerged and a lot of roots and branches: this is the perfect habitat for the Taeniacara candidi. They hide between the roots and inside the leaf litter layer on the shoreline where the water somtimes is less then 2cm above a thick layer of ficus leafs.
我复原了伊加拉佩普罗塞里塔特（Igarapé Prosperitate）河口的岸线。这里有沉没的树干以及大量的根系和枝条：这正是塔氏隐带丽鱼（Taeniacara candidi）的理想栖息地。它们藏身于根系之间，以及岸边的落叶层内部；在某些区域，厚厚的榕树叶层上方水深甚至不足 2 厘米。
Paracheirodon axelrodi live in large schools above the leaf litter.
阿氏霓虹脂鲤（Paracheirodon axelrodi）成群结队地游弋于落叶层上方。
Description of the Habitat Parameters: The tea colored water is acidic (pH 4.1 – 5), Gh 2-5°dH, 10-70ys/cm.
栖息地参数描述：水体呈茶色，具酸性（pH 4.1–5），总硬度（Gh）为 2–5°dH，电导率为 10–70 µS/cm。
Temperatures reach a maximum of 29.5°C. Upstream the water temperature is approximately 24°C, because the complete stream is in shade.
最高水温可达 29.5°C。上游水温约为 24°C，因为整条溪流都处于树荫之下。
