Betta mahachaiensis is a relatively new species of betta fish discovered in 2012 in the Samut Sakhon Province of Thailand. It is a member of the Betta splendens group but exhibits distinct characteristics that set it apart.

Physical Characteristics

• Body: Slender and elongated compared to the more common domestic Betta splendens. Reaches a maximum length of approximately 5-6 cm (2-2.4 inches).
• Coloration: Males exhibit a striking iridescent green-blue pattern on a brown-black background. Females are generally browner with hints of green.
• Fins: Fins are typically brown to black with iridescent green-blue interradial membranes. Dorsal fin often has black transverse bars.
• Opercular membrane: Lacking the red streaks or patches common in other Betta species. Instead, it has two parallel iridescent green or bluish-green vertical bars.
• Habitat: Found in brackish waters with salinity levels between 1.1 and 10.6 parts per thousand. Notably, this species can tolerate both freshwater and brackish environments.
