Coloração

Males exhibit a striking copper-orange to reddish-brown body coloration, intensifying during breeding. A prominent dark, horizontal stripe runs from the operculum to the caudal peduncle, terminating in a distinct black spot. The dorsal, anal, and adipose fins are typically translucent with a reddish tint. The most distinguishing feature is the white or silvery tip on the lobes of the caudal fin. Females are generally duller in coloration, with a more subdued copper hue and a rounder body shape, especially when gravid.

Dicas de identificação

1. 1

   Caudal Fin Tips

   Look for the prominent white or silvery tips on the upper and lower lobes of the caudal fin. This is the most reliable distinguishing feature.

2. 2

   Body Coloration

   Observe the overall copper-orange body color, especially in males. Females are less intensely colored.

3. 3

   Adipose Fin Absence

   Confirm the absence of an adipose fin between the dorsal and caudal fins. This differentiates it from many other tetra species.

4. 4

   Lateral Stripe and Spot

   Note the dark lateral stripe that extends to a distinct black spot on the caudal peduncle.
