Why Wild Bettas
Wild bettas display natural behaviors lost in domesticated splendens: subtle iridescent colors, complex social interactions, and (in some species) mouthbrooding paternal care.
Many species can be kept in groups (unlike splendens). Most prefer cooler, softer water. All require some level of biotope conditions.
Betta Imbellis (Peaceful Betta)
Native: Thailand, Malaysia, Cambodia.
Size: 2 inches.
Temperament: peaceful, can be kept in pairs or small groups in 20-gallon+.
Care: pH 6.5–7.5, soft water, blackwater conditions ideal.
Color: iridescent blue-green with red fin edges.
Betta Smaragdina (Emerald Betta)
Native: Thailand, Cambodia, Laos.
Size: 2.5 inches.
Temperament: similar to imbellis, peaceful.
Care: pH 6.5–7.5, soft water.
Color: striking emerald green with black markings.
Betta Macrostoma (Brunei Beauty)
Native: Brunei, Sarawak (Borneo).
Size: 4 inches.
Temperament: paternal mouthbrooder, paired only.
Care: pH 4.5–5.5, very soft water, cool (72–78°F). Highly demanding.
Cost: $200–600 per pair.
Betta Brownorum
Native: Sarawak, Borneo.
Size: 1.5 inches.
Temperament: paternal mouthbrooder, peaceful.
Care: pH 5.0–6.0, soft water.
Color: red body with black bars.
Betta Coccina (Wine Red Betta)
Native: Sumatra, Indonesia.
Size: 2.5 inches.
Care: blackwater specialist, pH 4.5–5.5.
Color: deep wine red with green spots.
Mouthbrooding Behavior
Many wild bettas (macrostoma, brownorum, channoides, picta) are paternal mouthbrooders.
After spawning, the male holds eggs and fry in his mouth for 10–14 days. Cannot eat during this time.
Spawning ritual: pair embraces, female releases eggs, male catches them and spits them onto his lower jaw to brood.
