Heckel Wild
Symphysodon discus
Description
The Heckel Wild is regarded by many collectors as the ultimate variety. This pure wild species showcases subtle natural coloring and the elegance of its 9 vertical bars, with the central bar (the 5th) being dramatically wider.
🌍 Origin & History
Rio Negro, Rio Trombetas, and Rio Abacaxis (Brazil). Scientifically described by Johann Jakob Heckel in 1840 — the first discus species ever identified. It lives exclusively in extremely soft and acidic blackwater.
Appearance
Brownish-red body with turquoise reflections on the forehead, operculum, and fins. Nine dark vertical bars, with the 5th (central) bar being very wide and black. Intense red eyes.
🧬 Genetic background
Symphysodon discus is one of the three recognized species (alongside S. aequifasciatus and S. tarzoo). The defining feature: the 5th vertical bar is much wider and darker than the other 8 bars — the Heckel signature.
Recommended water parameters
Care
Extremely demanding. Requires remineralized RO water at very low values, blackwater with catappa leaves and peat. Only for experienced breeders.
Breeding
Very challenging in captivity. Requires parameters identical to those of the Rio Negro (pH 4.5–5.5, TDS below 30 ppm).
💡 Practical tips
- →The wide central bar (5th) is the defining feature
- →Never below 28°C — the immune system is very fragile
- →Slow acclimatization over a minimum of 6–8 weeks
