General Description
The Betta Simorum belongs to the B. bellica group and is characterized by a long, slender body with iridescent green markings on dark brown scales. It differs from B. bellica in various features like head shape, fin ray counts, and scales. This species is part of the diverse Betta genus within the family Osphronemidae, known for adapting to various habitats from stagnant ditches to acidic peat swamp forests.
Aquarium Setup
To house Betta Simorum, a 72-liter tank is recommended without a substrate for easy maintenance. Decorate with driftwood, branches, clay pots, and leaf litter to mimic its natural habitat. Provide dim lighting, soft acidic water (pH 3.0-6.0), and gentle filtration. Include aquatic plants like Microsorum and floating vegetation. Access to a humid air layer above the water surface is essential.
Behaviour
Due to its sensitive disposition, Betta Simorum is best kept alone or with peaceful species. It may coexist with small cyprinids or other anabantoids with adequate space. Reports vary on group dynamics, with some suggesting pairs and others cautioning against aggression towards conspecifics from dominant individuals.
Feeding and Diet
Primarily insectivorous, Betta Simorum prefers odonate nymphs but accepts dried and live foods like Daphnia, Artemia, and bloodworms in captivity. Regular feeding is crucial for optimal health, although overfeeding should be avoided to prevent obesity, a common issue in Betta species.
Reproduction & Dimorphism
This bubble-nesting species requires ample cover for successful breeding. Males build nests for egg deposition, with females exhibiting paler coloration and dark bars during spawning. After hatching, fry rely on parental care. Mature males display more vibrant colors and slightly elongated fins compared to females.
Habitat and Distribution
In the wild, Betta Simorum inhabits heavily-vegetated forest peat swamps and blackwater streams with minimal dissolved minerals and low pH levels. Found in Sumatra and Borneo, this species thrives in dimly lit waters rich in decomposing organic material. Various localities in these regions serve as collection points to preserve distinct populations.
