Yes, after placing your order, you can email [email protected] with your color request. We will do our best to accommodate it based on availability.
Are the fish in this variety guaranteed to have the same color pattern?

Received my halfmoon betta and it’s vibrant and active. The black mustard gas color is striking and the fish swims with confidence. Great for a beginner who wants a colorful, lively betta.

The fish arrived healthy and showed good energy. While the color wasn’t exactly as pictured, it’s still a beautiful mustard gas pattern. I’m happy with the tank-bred quality.
Irene White –
This betta is a true standout. The halfmoon fin is well-developed and the fish is very active in the tank. I appreciate the variety and the care taken in breeding.
Gordon Buckland –
The fish looks good overall, but the coloration is a bit muted. I expected more vivid mustard gas, but it’s still a decent specimen for the price.
