Mustard Gas Halfmoon Betta
The Mustard Gas Halfmoon Betta is one of the most visually striking Betta splendens varieties, featuring a rich dark blue or teal body contrasted with bold yellow to orange fins — a coloration reminiscent of the "mustard gas" aesthetic that gives this fish its name. With a dramatic 180° Halfmoon tail and flowing finnage, this Betta is a favorite among aquarists seeking vibrant, high-contrast display fish.
🎨 Iconic Color Contrast
Mustard Gas Bettas are bred for their unique two-tone appearance: dark, often iridescent bodies paired with contrasting mustard yellow, orange, or gold fins. Fins may include a black or dark outline that enhances their flowing Halfmoon shape. Each fish is unique, with some displaying subtle variation in fin saturation and body iridescence.
Appearance & Traits
- 💛 Yellow to orange fins with possible black edging
- 💙 Dark blue, teal, or steel-colored body with iridescence
- 🌙 Full Halfmoon tail spread (≈180°) for maximum visual impact
Packaging & Sexual Dimorphism
All Bettas are sold as unsexed individuals. Full coloration and tail development become more apparent as they mature. Males typically exhibit longer fins and more vivid coloration, but young fish may take time to show their full potential.
Care & Tank Setup
