Identification Tips

  1. 1

    Body Transparency

    The most striking feature is its translucent body, which gives it an 'X-ray' appearance. This is a key differentiator from many other small tetras.

  2. 2

    Fin Coloration

    Look for the characteristic yellow and black markings on the dorsal, anal, and caudal fins. The reddish adipose fin is also a good indicator.

  3. 3

    Caudal Peduncle Spot

    A distinct black spot located on the caudal peduncle (the narrow part of the fish's body where the tail fin attaches) is consistently present.

  4. 4

    Size

    Adults typically reach a maximum standard length of 4-5 cm (1.6-2 inches).
