Keeping Betta rutilans from an Aquarist View


Betta rutilans can be housed in pairs, species tanks, and community tanks.  Pairs can be housed in a 5 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.
