#649: 110L Biotope Aquascape Rio Negro, Shallows

I don't believe your fluffy plant is Cabomba. It looks like R. wallichii in these photos. Also Echinodorus do not grow in these areas. Your water color is very close to natural as is your substrate and the branches.

Lovely aquarium where I like the effect the plants bring. People sometimes try to make things easy by not adding any and say that these hardly are available in a biotope.

Well I prefer the reflections of a biotope that focus on the small parts where plants ARE available.

The wood looks still a bit to clean and the arrangement of wood could be stronger.

Nice attempt at a Rio Negro biotope. Unfortunately I don't think the plant being used in Cabomba. Also some of the wood looks to be freshly cut and detracts from the natural feel of the biotope.

I watched videos of researchers diving the flooded Rio Negro which indicated slightly murky water with suspended materials, submerged plants, and leaf litter gracing the floor of the riverbed. I conducted painstaking research of various sites and reference materials, including the Lista de Especies da Flora do Brasil for plant species. I additionally watched videos of those swimming the Amazon and of ichytologists searching for fish in the waters of the Rio Negro. The flooded waters are in no way crystal clear, but rather are full of tree fall and suspended detritus. In certain shallow side pools, cabomba can be found swaying in the waters.
