The Halfmoon Koi Betta is absolutely stunning. Its vibrant colors and wide fins create a beautiful focal point in my tank. It’s more active than other Bettas and really draws attention. I love how unique it looks compared to standard Betta fish.

Received the fish in perfect condition. The colors are vivid and the fin spread is impressive. It’s a real eye-catcher in my 10-gallon tank. I’m very happy with the purchase.

The fish looks exactly as described. The koi-like pattern is beautiful. It’s a bit shy at first but becomes more active over time. I’d recommend it to anyone looking for a visually striking Betta.
