Keeping Betta akarensis from an Aquarist View


Betta akarensis 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 55 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.

Males are more intensely colored.  Males also have pointed dorsal and anal fins whereas females are rounder.


Akarensis is a paternal mouthbrooder.
