Materials Roots, branches and twigs covers a sandy substrate (0,4-1,2mm). Mix of peat, leaves, bark and small branches lays in the parts of tank with small current. Few bigger roundish rocks, and some gravel occurs in the main stream bed (place with bigger current on the right)
Additional Information My tank shows almost 2m wide, and 30cm shallow (in dry season) stream tributary to Rio Paragua. "Atypical" blackwater (according to Sioli definition) with water parameters closer to classical clearwater streams. Section with abrupt, eroded bank on the left side, under the roots of nearby tree. Roots slows water current, and it leads to create nice habitat for smaller fish like Apistogramma trifasciata and Aphyocharax rathbuni. Hydrocotyle leucocephala, growing emersed on bank and roots, keep the light low; small twigs, bark, leaves and other sediments gives good shelter and spawning area. Slower current creates a place with abundand food source, which is perfect for fry to raise. In front of bigger wood piece, that lay on the right part of stream section, some Eichhornia diversifolia grows in the area, where sunrays reaches bottom better. Stronger current occurs only in narrow, clear part of stream. Some gravel, and few roundish rocks lays there. This is the spot where mentioned fish swim only while migrating into planted area, or up/down the stream, and where Corydoras sterbai swim while searching for food in the stream bottom. Water is well oxygenated and a little turbid (much more in the rainy season).
