Keeping Betta rubra from an Aquarist View


Betta rubra can be housed in pairs, species tanks, and community tanks.  Pairs can be housed in a 20 gallon tank, groups should be housed in a 30 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.

Water Conditions

Betta rubra comes from blackwater environments and should have soft acidic water that is well filtered.  They should be kept at cool to mid 70s F.


Rubra males are more intensely colored then females.  Males have red opercular bars where as females bars will be gold.  Females ovaries might be visible via spotlighting. 


Rubra is a paternal mouthbrooder and the male incubates from 12 to 17 days with 15 days being very consistent.  Incubation time can vary with water temperature.  Females normally initiate spawning. 

Similar Species Similar species would be foerschi, strohi and mandor.  
Identification Foerschi and Mandor have red opercular bars, Strohi have gold bars.  Rubra have red opercular bars and males can exhibit red stripes in the body.
