Black Emperor Tetra
Black Emperor Tetra(Nematobrycon palmeri‘Amphiloxus Black’) is a captive-developed melanistic color morph of the Emperor Tetra — the body coloration is dramatically darkened to deep charcoal-black, while the most striking features are retained: the vivid turquoise-blue eyes glow even more intensely against the dark body, and males develop the same spectacular trident tail extensions and territorial display behavior as the standard form.
Feeding & Care Tip:Sera Vipan Tropical FlakesandHikari Micro Pelletsmake excellent daily staples. Supplement 2–3× per week withHikari Frozen or Freeze-Dried Bloodworms,Hikari Frozen or Freeze-Dried Baby Brine Shrimp, orHikari Vibra Bites. Feed small amounts 2–3 times daily.
The melanistic coloration is a selectively developed aquarium strain — the trade designation ‘Amphiloxus Black’ reflects its origins in selective breeding. All care requirements are identical to the standard Emperor Tetra.
Keep in mixed-sex groups of at least 6. Males display the same spectacular territorial fin-spreading as the standard form — the dark body makes the turquoise eyes appear even more luminous during these displays.
Excellent for planted aquariums where the dark body creates a dramatic silhouette against green foliage. The turquoise eye provides the only vivid color accent.
