Why is the X-Ray Tetra affectionately called the X-Ray Fish?
Answer
Its translucent body allowing a view of internal structure
The affectionate nickname 'X-Ray Fish' directly stems from a striking physical characteristic of the X-Ray Tetra: its body is largely translucent. This translucency allows observers, particularly those keeping the fish in aquariums, to clearly view the fish's underlying internal structure and organs. This visual quality is what draws comparisons to medical X-ray imaging. This trait is the primary feature distinguishing it visually in the trade and is directly linked to its common moniker, setting it apart from many other species that possess opaque or heavily scaled bodies that obscure their internal anatomy.
