Benjarong yellow males come from the wild-type side of the betta hobby: a line kept close to the species' natural form, finished in vivid yellow on a 6.5 cm fish with the trim fins and darting movement that ornamental strains traded away generations ago. The yellow is the draw — bright, clean and constant, without marbling or banding to dilute it.

His record allows a touch more flexibility than most wild types: peaceful small fish that neither nip fins nor resemble him in colour or shape are listed as possible, alongside snails and some peaceful bottom-dwelling shrimp — with individual males still liable to hunt them. Firm exclusions: other male bettas, fin-nippers, aggressive or highly territorial fish, large predators, long-finned or similar-bodied fish, and small shrimp or fry, which he will treat as food. He is aggressive in grading, moderate in care, and specific in water: 24–30 °C, pH 6.0–7.5, and a softer 1–12 dGH hardness ceiling shared with our other wild lines. A 20-litre tank is the recorded floor. He occupies the upper water, eats as a carnivore, and turns territorial in season.

His record's tank-mate logic deserves a careful read: possible companions must be peaceful, must not nip, and must not resemble him in colour or shape — which in yellow rules out more candidates than keepers expect. Small drab schooling fish pass the test; anything golden, flowing or betta-shaped fails it. The same record sets his water softer than ornamental lines at 1–12 dGH, so verify your supply first. After that he is a 20-litre-minimum fish with a heater pinned in 24–30 °C, carnivore meals — wild lines repay frozen and live variety with stronger colour — and pH held between 6.0 and 7.5. Plant generously: cover is how wild-form bettas regulate their own confidence, and a confident fish shows the deepest yellow.

    I have a small group of long finned mountain minnows. So was delighted to be able to order ten of this variety to increase the genetics in my tank . The ones I recieved are healthy but it’s to early to give a verdict on wether they are of a long finned type since they are small currently.

    100% success travel and "installation". Pleased with quality of purchase. The Siamese fighter a bit "shy" so have not yet seen him at his best yet but looking good. Happy customer. GG
