Betta siamorientalis is a small, wild betta species from Southeast Asia, known for its dark, blackish body and reddish fins, often called the "black imbellis" due to its resemblance to B. imbellis. It's a bubble-nesting fish found in shallow, vegetated waters like marshes and rice paddies, and it's a facultative air-breather, meaning it can breathe atmospheric air. This species is distinct from B. splendens and is characterized by its slender body, red vertical bars on the opercle (gill cover), and a red crescent on the caudal fin.
Key Characteristics
- Appearance: Dark brown to black body with iridescent green/blue accents; males have red patches on fins and reddish bars on the opercle; females are duller.
- Size: Small, reaching a maximum of about 3.6 cm (1.4 inches).
- Habitat: Still, shallow freshwater in eastern Thailand, Cambodia, and Vietnam, often among dense aquatic plants.
- Behavior: Males build bubble nests and are territorial, but can be kept in groups if there's enough space and plants to establish territories. They are known jumpers.
- Diet: Carnivorous; accepts high-quality pellets and live/frozen foods.
- Care: Prefers planted tanks with tannins (from leaves) to mimic its natural habitat, stable warm water (24–28°C), and a secure lid.
Identification
- Often confused with B. imbellis, but B. siamorientalis has a darker body and lacks the facial iridescence of B. imbellis.
- DNA analysis confirmed it as a separate species from B. splendens and B. imbellis.
