My biotope is a small piece of the Tapajos River. The motivation for my biotope was the difficult to maintain plant Syngonanthus macrocaulon, running in the aquaristics under commercial name Tonina sp. Belem, which was first discovered in the Belem area.
The composition is created from driftwood, river stones, river pebbles, light quartz sand and fallen leaves of various drying.
Water change 1 time per week from reverse osmosis using Prodibio GH+ remineralizer. Control of parameters GH,pH, NO3, PO4. Oase Organix Daily Feeding.
Fishes:
Prodac Nutrient Pad, Prodibio Liquid Fertilizers.
Plants:
Here weekly 20-50% osmotic water change using a remineralizer.
Roberto E. Reis: No BIN information provided. Very nice tank, with plants, roots, stones and leaves. Only one fish species, apparently only three specimens.
Flavio Lima: As the author did not provided any information on the original biotope, it is not possible to evaluate that. It is a beautiful recreated set-up, although biotopes from the rio Tapajós that I have visited that included loose sandstones and sand typically does not have peebles, only rocks and sand. Also, Prionobrama is a species more typical from floodplain lakes, so does not match perfectly the intended biotope. There are several types of biotopes in the rio Tapajós, and I assume that the participant was trying to recreate a more riverine habitat, so a fish like Hemiodus gracilis would have been a better choice.
