Natural habitat
Betta anabatoides lives in lowland rivers and streams of southern and central Kalimantan (Indonesian Borneo). It has been collected from a sluggish, murky stream up to about 1.2 m deep.
Where they are found
Endemic to Indonesian Borneo: the lower Barito basin in South Kalimantan and the Kotawaringin, Katingan, Sampit, Mentaya and Kahayan basins in Central Kalimantan. It is a wild species. The "giant" or "king" betta sold as a large form of Betta splendens is a different fish.
Aquarium care
Giant Bettas require a well-maintained aquarium of at least 40 liters to accommodate their size and preferences for gentle, stable conditions. Regular water changes and effective filtration are critical to avoid stress-induced health issues. They thrive in aquariums with soft substrates, ample plant cover, and subdued lighting, allowing them to feel safe and secure.
Feeding
Giant Bettas require a high-protein diet rich in animal matter. Foods such as high-quality pellets, live or frozen food like bloodworms or brine shrimp are essential for their health. Feed them based on their appetite and avoid overfeeding to maintain water quality.
Compatibility
Giant Bettas are peaceful and can coexist with other gentle species in a community tank. However, they should not be housed with aggressive or overly boisterous tankmates that could induce stress.
Breeding
A paternal mouthbrooder of the Betta anabatoides group. The male incubates the eggs in his mouth until the fry are free-swimming. It does not build bubble nests.
