The X-Ray Tetra (Pristella maxillaris) is a small, transparent freshwater fish native to the coastal rivers of South America, particularly in Brazil, Guiana, and Venezuela. It is named for its translucent body, which reveals its internal structure, resembling an X-ray. The X-Ray Tetra features a distinctive black, white, and yellow pattern on its dorsal and anal fins, adding to its unique appearance. Known for its peaceful nature, this fish is ideal for community aquariums, thriving in schools and requiring well-planted tanks with soft, slightly acidic water.
