Description of the Area Surrounding the Biotope: The Nanay River is a river in northern Peru. It is a tributary of the Amazon River, merging into this river at the city of Iquitos.
The lower part of the Nanay flows to the north and west of the city, while the Itaya River flows to the south and east.
The Nanay belongs entirely to the lowlands, and is very crooked,
has a slow current and divides into many canos ( canal ) and strings of lagoons which flood the flat, low areas of country on either side.
It is simply the drainage ditch of districts which are extensively overflowed in the rainy season.
A part of the Nanay River flows through the Allpahuayo-Mishana National Reserve.
The Nanay is a blackwater river and it has a high fish species richness, including several that are well known from the aquarium industry.
Some of these, are P. Scalare Rio Nanay.Pterophyllum aitum,Pristella maxillaris .
