About the Mamberamo River
The Mamberamo is the second longest river in Papua New Guinea after the Sepik River. It is home to most of the uncontacted peoples of New Guinea, but most famously, the home of the dwarf rainbowfish (Melanotaenia praecox). The River is the third largest by discharge in Oceania after the Fly River and the Sepik. The pH of the River is 6.5 to 7.8. The River is set in mighty lowland and swamp rainforests, which itself is an important ecosystem for the many animals that live here.

Dwarf Rainbowfish
The dwarf rainbowfish (or dwarf neon rainbowfish) is endemic and common to the Mamberamo. The males are very colourful, while females are slightly drab. These fish display a beautiful blue body with red fins. They are 8cm in size, so you will need at least 30 gallons to accommodate them. These fish live in dense aquatic vegetation and congregate in submersed roots or logs. The dwarf rainbowfish requires hardwater to thrive. Perth water is an example of hardwater where the fish lives.

How to make a Mamberamo biotope
This biotope is one of the most unique in the world of biotope aquaria. The riverbed contains river sand mixed in with rocks and rainforest litter. Larger rocks can be used for the background of the setup, driftwood may be included as well. You will need those things for the setup because you want to recreate the fish's natural habitat as closely as possible. Crushed root tabs are required for the setup for plant root growth in the substrate. The River contains various unique aquatic plants such as Nymphaea, Microsorum pteropus, Vallisneria nana and Aponogeton species. Always place the larger plants in the background and the smaller ones in the background.
