Keeping Betta strohi from an Aquarist View


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


Strohi 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. 


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

Differentiation From Similar Species: [Betta strohi differs from Betta foerschi in that] they have yellow gill plates. [7]

As for B. foerschi and B. strohi, I do think they are probably distinct species, based not only on morphology but on coloration, size and behavior.

The majority of the morphological reason for splitting B strohi off was based on radically different jaw structure in the males, not coloration as is widely believed due to just a few photos circulating around of these fish (i.e. B. foerschi has "red" bars, B. strohi has "gold" - sometimes these fish have red bars, sometimes they're gold - on the same fish!). Now that they are becoming available, maybe with more observations by more folks working with them, this will change.

From my experience with B. foerschi, and now working with these beautiful fish, I see some distinct differences. The B. foerschi I kept were more reddish or rust colored while these are bluish and much darker. My B. foerschi, while still a slim fish, were a bit larger and more heavy bodied in comparison too. Also, B. foerschi spent more time in the open and near the surface and was a much more active swimmer, while these strohi, at least, spend most of their time down low, lurking under leaves and don't swim about very much, except when food is in the water!
