Natural habitat
Betta ferox was described from a small, flowing river with a gravel and sand bottom at Bori Pat in southern Thailand. The fish lived along the banks in slower water among roots and aroid plants. The water was soft and slightly acidic (pH about 5.8–6.3) at around 23–26 °C.
Where they are found
Endemic to southern Thailand. It is known from the Bori Pat area of Songkhla Province.
Aquarium care
Keep in a covered tank with gentle to moderate flow, a sand or fine gravel bottom, and roots and plants for cover. Soft, slightly acidic water at moderate tropical temperatures suits it.
Feeding
Bettas are micropredators and thrive on a protein-rich diet. They should be fed high-quality betta pellets, complemented with occasional treats like live blackworms and brine shrimp. Portion control is essential to prevent overfeeding issues.
Compatibility
Bettas can be aggressive, particularly males, and should generally not be housed with other male bettas. Suitable tankmates are small, peaceful fish that occupy different swimming levels. Always monitor to ensure compatibility.
Breeding
A paternal mouthbrooder of the Betta pugnax group. The male incubates the eggs in his mouth until the fry are free-swimming. It does not build a bubble nest.
