- Habitat
- Forest streams
- Size and measurement
- 67.0 mm standard length is the maximum reported in Tan & Ng (2005). Standard length excludes the caudal fin; this historical sample is not a guaranteed captive adult maximum.
- Planning context
- A mouthbrooding forest-stream species. Confirm the source population, feeding history and adult dimensions before choosing a system. Field measurements are observations, not a universal aquarium recipe.

Plan around the wild species
Care-planning notes. Confirm exact requirements for the species and source population.
- Wild Betta have different habitats and breeding strategies; ornamental Betta splendens advice cannot cover every species.
- Retain species and locality records, and verify whether the line is a bubble-nester or a mouthbrooder.
- Plan a secure cover, shelter and a species-specific social arrangement before acquiring a line.
