Betta Marcostomus

Betta macrostoma is a species of fish in the Betta genus, native to the freshwater rivers and streams of Borneo and surrounding areas. It is sometimes called the “Brunei beauty” due to its stunning appearance. Here are some key details about Betta macrostoma:

• Appearance: Betta macrostoma is known for its vibrant colors, particularly its red and blue hues. Males are especially colorful, with elongated fins that can be quite striking. They also exhibit a complex pattern of markings across their bodies.
• Size: These fish are relatively small, typically growing up to 3-4 inches (7-10 cm) in length.
• Habitat: This species is found in slow-moving streams, typically in forested areas with clear, slightly acidic water. They prefer water temperatures ranging from 75F to 80F (24C to 27C).
• Diet: They are carnivorous and primarily feed on small invertebrates, such as insects, larvae, and zooplankton in the wild.
• Behavior: Like many bettas, Betta macrostoma can be territorial, especially males, who are often aggressive towards each other. However, they are typically peaceful with other species of fish that aren’t too aggressive.
