Green Alien Betta 3cm Sexed or Pairs

The Green Alien Betta (Betta sp. ‘Alien’) is a striking hybrid Betta developed from wild Betta smaragdina and related species, prized for its extraordinary metallic green iridescence and elongated, alien-like body shape. Unlike traditional splendens-type Bettas, the Alien Betta has a more slender, torpedo-shaped profile with vivid scale patterning that shimmers under aquarium lighting — a truly unique and conversation-starting fish for the discerning Betta collector.
