Mustard Gas Betta

The Mustard Gas Betta is one of the most striking betta colour variants available. With a deep royal or steel blue body and contrasting vibrant yellow or golden fins, this betta’s appearance is both bold and elegant. The name "Mustard Gas" comes from the dramatic gas-like transition between its dark body and lighter, glowing fins. Ideal as a centrepiece fish, it adds instant visual impact to any aquarium.

While they can tolerate cooler water and live in tanks without heaters, the very cold winters in South Africa can be tough on them. Providing a heater during colder months helps maintain stable, warmer water temperatures — leading to healthier and happier fish.

Bettas thrive on a high-protein diet. Feed them quality betta pellets, frozen foods like bloodworms, daphnia, and brine shrimp to support vibrant color and overall health.

Adding supplements like Seachem Garlic Guard and Azoo Discus Vitamins to your betta’s diet can help boost immunity, improve appetite, and keep your fish in peak condition. These extras, combined with a balanced high-protein diet, go a long way in supporting your betta’s overall health and vibrancy.
