Identity and origin
- Origin
- Kapuas and Mahakam basins, Kalimantan; also Sarawak
- Identity
- Bornean giant gourami with Indonesian native records
A separate giant-gourami species recorded in western and eastern Kalimantan. This is a specialist biodiversity record: its large adult size makes long-term space and welfare central to any ornamental use. It is not the red-tail gourami O. laticlavius.
Habitat and care
Freshwater in Bornean river basins. Habitat and identity reference
FishBase reports up to 50 cm standard length. Specialist large-system planning and verified identification are essential.
Before choosing this species
Care-planning notes. Confirm exact requirements for the species and source population.
- Confirm the adult size and social behaviour of the exact species before planning its aquarium.
- Establish biological filtration and stable water conditions before introducing animals.
- Ask for locality, captive history and the actual animal’s feeding record; a catalogue image cannot provide these.
