Keeping Betta dimidiata from an Aquarist View
Betta dimidiata can be housed in pairs, species tanks, and community tanks. Pairs can be housed in a 10 gallon tank, groups should be housed in a 20 gallon tank or larger. Pairs should be given cover such as caves and plants. In a pair or species situation it is possible that fry could be discovered in the tanks. For best results remove a brooding male.
Not critical, dimidiata is very tolerant of water chemistry and thrives in almost any type of water as long as it is clean and well filtered. They should be kept at cool to mid 70s F.
Dimidiata males are more intensely colored then females. Males may also show a brilliant band in the anal and tail fins. Females ovaries might be visible via spotlighting.
Dimidiata is a paternal mouthbrooder and the male incubates from 7 to 12 days with 9 days being very consistent. Incubation time can vary with water temperature. Females normally initiate spawning.
