Natural habitat

Betta albimarginata inhabits shallow forest streams in the Sebuku River basin of East Kalimantan, Borneo, characterized by soft, acidic waters with a fine silty substrate and leaf litter from the surrounding forest.

Where they are found

This species is endemic to eastern Borneo, where forest streams and peat swamps are vital to its habitat. These natural environments are threatened by human activities such as drainage, mining, and agricultural conversion.

Aquarium care

Keep the aquarium water clean with frequent water changes and ensure the tank is heated between 24-27° C. Include plants and decorations for hiding spots to reduce stress. Regular water testing is advisable to maintain suitable water parameters.

Feeding

Feed Betta albimarginata a varied diet of frozen and live foods, including small worms, insect larvae, and zooplankton, supplemented with prepared foods high in insect protein to mimic their natural feeding habits.

Compatibility

Betta fish can be territorial and aggressive, especially males. They should not be housed with other males or fin-nipping species. Peaceful tank mates like certain tetras can sometimes be suitable, yet caution is advised.

Breeding

Breeding occurs when males attract females through courtship displays. It is mouthbrooding, with males collecting and caring for the eggs until they are ready to be released.
