My Amazon black water biotope Lago Manacapuru

A black water biotope of the region of Lago Manacapuru. Tank: 400l with a elevated plant filtration system. Fish: 10 F2 Pt. scalarae Manacapuru, A scool of Serpae tetras ( Hyphessobrycon eques), 5 Ancistrus dolichopterus, 12 Korydoras panda, a pair of apistogramma cacatuoides. It is not 100 accurate biotope, but in my opinion it s close enough.
