Green neon tetra

Paracheirodon simulans

A long blue-green stripe and little red

The bright stripe reaches the tail base. In neon and cardinal tetras it ends farther forward, near the adipose fin.

Use a mature, stable aquarium. Avoid extreme pH adjustments.

Appearance and identification

Compare the amount of red as well: the cardinal has a much more extensive red flank.

Keep at least 8–10 together; they may not school tightly all the time.

At least 45 × 30 cm. Provide cover and make sure these small fish can reach food.

Provide tiny dry foods and small live or frozen foods; check that small-mouthed individuals get enough.

Avoid larger, forceful competitors.

Plants can offer cover, but stable water and gentle maintenance matter more than layout alone.
