Rare Captive-Bred Betta Macrostoma Juvenile Pair (F1) – 6 Months Old

Why Captive-Bred Betta Macrostoma is the Smart Choice

Betta macrostoma, also known as the Brunei Beauty, is prized for its dramatic coloration and gentle nature. Unfortunately, wild-caught specimens are highly sensitive, often arriving stressed, malnourished, and prone to disease.

That’s why this captive-bred F1 juvenile pair offers such incredible value. Born from wild parents in controlled, aquarium environments, they’ve never experienced the harshness of wild capture or long-distance shipping. Instead, they come to you strong, stable, and ready to flourish in a well-maintained tank.
