Brachyhypopomus cunia
Brachyhypopomus cunia is a small electric knifefish found in tropical freshwater rivers and streams of South America. It grows up to 17.6 cm and is known for its weak electric organ used for navigation and communication, making it a niche target for scientific collectors rather than sport anglers.

BrazilClear blackwater stretches of the Rio Negro host dense populations of Brachyhypopomus cunia, especially around submerged root systems and flooded forest islands.
Best: June-September
Lake Maracaibo
VenezuelaThe brackish western basin of Lake Maracaibo offers abundant soft‑mud habitats where this electric knifefish thrives during the rainy season.
Best: May-October
