INFORMATION ABOUT BIOTOPE
Description of the area surrounding the biotope: Caño Tarapoto is one of the many tributaries of the Nanay River with black water, it is home to a great variety of species of ornamental and edible fish, which is used in the villages that are on its banks. Caño Tarapoto is the ideal habitat for cichlids like angelfishes, apistogrammas and the impressive discus fish, as well as plecos, tetras, catfishes, etc.
Description of the underwater landscape of the biotope: The underwater environment mainly consists of submerged roots of trees that die from stationary floods, small trunks and a large amount of leaves in the riverbed, which gives the water its particular brownish hue. The bottom consists mostly of gravel and white sand. An approximate depth in drainage is 5 meters and 10 to more meters in rainy season. In the black water visibility tends to be an average of 40 cm approximately. This depends also of the time of the year, since in the rainy season the visibility and transparency of the water increases.

Comments of the members of the jury of Biotope Aquarium Design Contest 2018
Interesting design, but this tank is not a good home for this amount of fish. Not a good combination. Some grow too big for a 350 liter tank. And there is definitely a shortage of hiding places in this tank.
