Stunning Guide to Metallic Betta Fish: Beauty, Genetics, and Expert Care Tips
What Is a Metallic Betta Fish?
Genetic Background and Appearance
The Metallic Betta Fish is a shimmering marvel in the aquarium world. First selectively bred around 2017 in parts of Asia, this variety is a refined blend of koi, nemo, and multicolor betta strains.
Breeders aimed to enhance the ornamental quality of traditional bettas by evolving their scale texture and color patterns. What emerged was a dazzling spectacle—metallic bettas with celestial-like, iridescent scales.
At the heart of their unique appeal is the Galaxy Metallic Scale trait. These tiny, reflective scales glitter like stars and are predominantly found along the fish's back and midsection. Complementing this are blue metallic overlays—patches of saturated blue scattered unevenly across their bodies and fins. These overlays contrast dramatically with red, orange, or yellow undertones, making every metallic betta uniquely mesmerizing.
Males typically sport bolder, more extensive metallic flake coverage, with galaxy-like shimmering scales on the top and midline. Females often show subtler metallic tones with a modest sheen. The base coloration ranges from red to orange, overlaid with iridescent silver-blue or turquoise hues
Metallic vs Alien Betta vs Dragon Betta

Metallic Betta: Distinguished by shimmering reflective scales (iridophores) over a solid base color, giving a steel, turquoise, or copper glint.
-
Alien Betta: Mostly characterized by strong contrast scales in a mesh or alien-like pattern, often silver or steel, commonly crossing with Metallic lines.
-
Dragon Scale: Thick, raised scales with extra keratin, giving a dragon-like armor texture.
