LiveAquaria Halfmoon Betta (Male)
Give your freshwater aquarium fantastic flair with the addition of a Halfmoon Betta. The handsome Halfmoon Betta is a premium variety of Betta splendens that has been selectively bred for its highly ornate fins and caudal (tail) fin that forms a distinct semicircle or “Half Moon” shape with a spread of 180 degrees. This dramatic caudal spread makes the showy Premium Halfmoon Betta a true piscine peacock sure to draw wanted attention to your freshwater aquarium landscape.
The Halfmoon Betta shares the same care requirements as other Betta splendens varieties. As such, only one male Betta should be kept in an aquarium. However, the smaller, shorter-finned females may be housed together with caution. If kept in a community aquarium, the Premium Halfmoon Betta should be placed in a well-planted tank with compatible species.

The Halfmoon Betta is absolutely stunning. Its tail spread is impressive and it adds a lot of visual interest to the tank. I’ve had it for three months and it’s very active and healthy. Only keep one male, as it can be aggressive toward others.
Gordon Hart –
Beautiful fish with a unique appearance. It’s not the most active, but it’s peaceful and stays in one area. I keep it in a 10-gallon tank with some plants and it’s doing well. Needs stable water conditions.

The color and shape of the tail are exactly as described. It’s a showy fish that draws attention. I’ve never seen a Betta with such a full tail spread. It’s easy to care for and stays calm in a well-planted tank.
