Betta channoides, also known as the "Snakehead Betta," is a small freshwater fish from the family Osphronemidae. It is one of the species commonly referred to as a "bubble-nesting betta" due to its unique breeding behavior.
Key Characteristics:
-
Appearance:
- Betta channoides has a slender body with vibrant coloration. Males exhibit bright red to orange hues, often with black markings on their fins and body. Females tend to be less colorful.
- The fish's size is relatively small, reaching about 5-6 cm (2-2.5 inches) in length.

Habitat:
- It is native to Borneo, specifically in the blackwater streams of the Kapuas River basin in Indonesia.
