The Mamberamo River - Papua New Guinea's Hidden Gem
The Mamberamo River is Papua New Guinea's second longest river, after the Sepik River. Home to many uncontacted peoples of New Guinea, it's also famous for being home to the dwarf rainbowfish. The river ranks third in terms of discharge in Oceania, after the Fly River and the Sepik. Its pH levels range from 6.5 to 7.8. The river's ecosystem, set amidst lowland and swamp rainforests, is crucial for the many animals that call it home.

The Dwarf Rainbowfish
Dwarf rainbowfish are endemic to the Mamberamo. They're quite a sight to behold, with males displaying vibrant colors and females being slightly more subdued. Their beautiful blue body with red fins is a treat to see. Reaching a size of 8cm, you'll need at least 30 gallons of space to accommodate them. They thrive in dense aquatic vegetation, often congregating in submersed roots or logs. Hardwater is essential for their survival, with Perth water being a great example.

Recreating the Mamberamo Biotope
This biotope is one of the most unique in the world of biotope aquaria. To recreate it, you'll need a mix of river sand, rocks, and rainforest litter for the riverbed. Larger rocks can be used as a backdrop, and driftwood can be added for a more authentic look. Crushed root tabs are necessary for plant root growth in the substrate. The Mamberamo is home to unique aquatic plants like Nymphaea, Microsorum pteropus, Vallisneria nana, and Aponogeton species. Place the larger plants in the background and the smaller ones in the foreground.
