Housing

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

Sexing

Foerschi 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.

Reproduction

Foerschi 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 mandor, strohi and rubra.
Identification Foerschi and Mandor have red opercular bars, Strohi have gold bars.
