Betta - Macrostoma (Betta macrostoma)

The Betta macrostoma, commonly known as the Spotfin Betta or Brunei Beauty, is a highly sought-after, vulnerable species of wild betta endemic to the island of Borneo. Unlike the common Betta splendens, it is a paternal mouthbrooder and requires specific, stable water conditions, making it a fish for experienced aquarists.

Key Features:

  • Semi-aggressive. Ideally kept as just a pair in the tank. 
  • Temperament - due to their specific environmental needs and potential territoriality, they are best kept in a species-only tank
  • Moderate care level
  • Maximum size: 10-12cm
  • Ideal water temperature: 18.0°C - 24.0°C
  • pH range: 4.0 - 7.0

It is found exclusively in Brunei and the northern part of Sarawak, Malaysia. It inhabits shallow, slow-moving, shaded forest streams and stagnant pools, often with a substrate of leaf litter and gravel, resulting in clear, highly acidic (pH 4.0-6.0) blackwater conditions. Ideally replicating these conditions brings out the best in this fish.
