Keeping Betta falx from an Aquarist View
Housing |
Betta falx 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, falx 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 |
Falx 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
simplex, picta and taeniata. |
Identification |
Falx males normally do have a highly pronounced
stripe in the caudal fin like simplex where as picta does not. |
