DescriptionEdit

They typically grow up to 3.5 centimetres (1.4 in) TL in length. Like their name implies, they are typically solid red with males of the species being more intensely colored, but a few rarely have green side. Males have more-so pointed dorsal fins and longer pelvic fins. Females are generally rounder and have an egg tube.[4] They will consume insects and small invertebrate.[3]

ReproductionEdit

Like most Betta fish, they breed in bubble-nests built to house the fry. Strangely enough, some have been seen to mouthbrood. The cause of this difference is unknown.[4]

CaptivityEdit

This species has been collected for use in aquariums for their intense color. They can be housed in community tanks with proper hiding spots in place and tank adequately sized for the amount of fish and species. They are from blackwater environments and should be housed in warm water with filtering.[5]
