Premium Mustard Gas Halfmoon Betta Male | WYSIWYG

This Premium Mustard Gas Halfmoon is all about contrast. A deep velvet-black body gives way to rich golden-yellow finnage before fading into a soft smoky blue edge, creating a colour combination that never seems to lose its appeal.

Selected for the Spectral Collection, this is a fish that stands out through balance rather than excess. Under the right lighting the colours constantly shift, making him just as enjoyable to watch months down the line as he is on day one.

As always with Obsidian Betta Co., this is the exact fish you'll receive. Every betta is individually selected for quality, health and presence before earning a place on the website.

Whether you're looking for a striking display fish or a quality addition to a breeding programme, this male is more than capable of becoming the centrepiece of the aquarium.

About the Spectral Collection

The Spectral Collection celebrates bettas with exceptional colour expression and visual impact. Rather than focusing on a single bloodline, these are fish chosen because they stop you scrolling and keep drawing your eye back to the aquarium.
