Rio Poranga, Upper Rio Negro, Brazil

Sponsored by

Brazil, State of Amazonas, Sao Gabriel da Cachoeira

The 240L aquarium is built and composed of fine beige sand and a layer of leaf litter, on top of that there are several branches and driftwood. The twigs and sticks are positioned so that it recreates the root systems of trees and other terrestrial vegetation sticking into the waterline,

I also have the root system of a live Monstera sp. plant positioned in the waterline that is allowed to grow totally natural in the aquarium, which also creates hiding spots for the aquarium inhabitants.

Aquarium description

Set-up date

Aquarium decoration

The two main things I focused on with this biotope was to have a thick layer of fine sand and leaf litter. I also added palm fibers and leaves just as in the natural biotope. On top of this I had a the root system of a terrestrial plant added namely Monstera sp. this is placed alongside twigs and branches sticking into the water.

Aquarium equipment
  • Filtration: Aquael Turbofilter 1500 and a small air driven sponge filter.
  • Lights: 2 blue and white ledlists for aquarium, each positioned about ten centimetres above the water.

Fish:

  • Apistogramma mendezi (Cichlidae)
  • Hyphessobrycon sp. (Characidae)
  • Hyphessobrycon socolofi (Characidae)
  • Petitella bleheri (Characidae)
  • Corydoras duplicareus (Callichthyidae)

Wetland plant:

  • Monstera sp.
Fish care

The biotope recieves a 30-50% waterchange every two weeks. The fish are fed wth Dennerle neon and Co booster they are also fed live and frozen brineshrimp.

Plant care

Comment by the expert

Roberto E. Reis: Fish and decoration selected properly, with five fish species listed – but two species not listed (Paracheirodon axelrodi and Petitella rhodostomus) do appear in the aquarium video. The aquarium looks attractive, with tank and fish displayed in two photos and one short video. Description of tank and external resources good.

Flávio Lima: That is a very well recreated biotope, with a lot of attention to details. The participant has really endeavored to recreate the complex, intricate aquatic habitat that can be found in a forest stream like the igarapé Poranga.

Pablo C. Lehmann: Aquarium very well structured, balanced, good light management representative of the natural habitat, with a significant composition of fish species.
