Keeping Betta picta from an Aquarist View

Housing

Betta simplex can be housed in pairs, species tanks, and community tanks.  Pairs can be housed in a 2.5 gallon tank, groups should be housed in a 10 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

Not critical, simplex is very tolerant of water chemistry and thrives in almost any type of water as long as it is clean and well filtered.  They should be kept at cool to mid 70s F.

Sexing

Males have a broader head then females and a much darker stripe on the anal fin.  Females may not have a stripe or faint stripe on the anal fin.  Females ovaries might be visible via spotlighting.

 

Reproduction

Simplex is a paternal mouthbrooder and the male incubates from 9 to 12 days with 10 days being very consistent.  Incubation time can vary with water temperature.  Females normally initiate spawning.

Similar Species Similar species would be picta complex members picta, falx and taeniata.
Identification Simplex males normally do not have a highly pronounced stripe in the caudal fin where as falx and simplex do.
