Tips Identifikasi

1. 1

   Coloration

   Look for the characteristic golden-yellow to brassy body color, which can appear iridescent under certain lighting conditions. This is the primary distinguishing feature from other tetras.

2. 2

   Size and Body Shape

   Observe its small, elongated, yet relatively deep body shape, typically reaching up to 4.5 cm. This helps differentiate it from more slender or larger tetra species.

3. 3

   Absence of prominent stripes/spots

   Unlike many other tetras (e.g., Neon Tetra, Cardinal Tetra), Hemigrammus rodwayi lacks prominent bright red or blue stripes, or distinct black spots on its body, relying instead on its overall golden hue.

4. 4

   Adipose Fin

   Confirm the presence of a small adipose fin, a common feature among characins, to help confirm its family classification.
