Keeping Betta miniopinna from an Aquarist View


Betta miniopinna can be housed in pairs, species tanks, and community tanks.  Pairs can be housed in a 5 gallon tank, groups should be housed in a 20 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.

Water Conditions

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


Females have an egg tube.  Females ovaries might be visible via spotlighting. Males may be more intensely colored and have pointed dorsal fins.  Females are rounder and show an egg spot.


Miniopinna is a submerged bubblenester so large leafed plants or black plastic film canisters are best for giving them a place to nest.

Similar Species Similar species would be all coccina complex members.
Identification The primary difference between B. persephone and B. miniopinna is the number of predorsal and lateral scales. Another difference may be the color of the pelvic fins, red in B. miniopinna and black in B. persephone, although persephone has also been known to exhibit red pelvic fins.  All other coccina complex members are red.
