SERPAE TETRA
Serpae tetras originate in the Amazon basin, inhabiting the Guaporé and Paraguay River basins in Argentina, Brazil, and upper Paraguay. Most specimens currently sold in the aquarium trade are captive bred rather than wild-caught; the species is not endangered. In the wild, this species prefers still and slow-moving backwaters such as lakes, ponds, and streams. They often congregate around tree roots and thick vegetation where they can find both safety and food
