How to Identify Green Neon Tetra

To identify Green Neon Tetra (Paracheirodon simulans), look at these key features.

Physical Characteristics

Body shape

elongated

Coloration

The most striking feature is a brilliant, iridescent blue-green lateral stripe that extends from the snout to the caudal peduncle. Below this stripe, the body is silvery-white, often with a faint reddish hue on the ventral side, particularly towards the caudal fin. The dorsal surface is typically olive-brown. The fins are largely transparent.

Scale type

cycloid

Mouth position

terminal

Distinctive features

Prominent iridescent blue-green lateral stripe, Absence of a distinct red stripe below the iridescent stripe (unlike P. innesi and P. axelrodi), Smaller adult size compared to other Paracheirodon species

Dorsal fin

Single, small, and typically transparent.

Tail fin

Forked, transparent.

Pectoral fin

Small, transparent, positioned ventrally.

Distinctive fins

Adipose fin present, typical of characins, small and transparent.

Identification Tips

1. 1

   Lateral Stripe

   The iridescent stripe is a consistent blue-green, running the entire length of the body. Unlike the Neon Tetra (P. innesi) and Cardinal Tetra (P. axelrodi), it lacks a prominent red stripe beneath the iridescent one. If a red stripe is present, it is very faint and restricted to the posterior half of the body.

2. 2

   Size

   Green Neon Tetras are generally smaller than both Neon and Cardinal Tetras, reaching a maximum standard length of about 2.5-3 cm (1-1.2 inches).

3. 3

   Body Shape

   They tend to have a more slender and elongated body profile compared to the slightly deeper-bodied Neon Tetra.

4. 4

   Eye Color

   The upper half of the eye often shows a reddish or orange tint, which can be a subtle distinguishing feature.
