Oversized pectoral fins on a short-finned female plakat make for an unusual combination: the body stays compact and athletic while the big ears flare out either side of the head like wings. This mixed-colour female line runs to about 6.5 cm and pairs that look with the hardiness plakat-type bettas are known for — no trailing finnage to snag, tear or weigh her down.

Despite being female, her record advises caution on company. She is semi-aggressive and the guidance is to keep her alone, or with very carefully chosen peaceful tank mates in a larger, heavily planted aquarium. Peaceful snails are reliable; peaceful shrimp may be compatible though hunting is possible. Avoid other bettas of either sex, fin-nipping species, large or aggressive fish, fast boisterous tank mates, and anything requiring markedly different water conditions. The recorded minimum is a roomy 40 litres, with water held at 24–28 °C — note the slightly narrower temperature band than many of our betta lines — pH 6.0–7.5 and hardness 1–15 dGH. Expect her in the top portion of the tank, and expect territorial behaviour to sharpen at times.

Hardiness is this female's quiet selling point. Short plakat fins mean no fin-rot anxiety, no flow restrictions and no surface-resting requirements — she handles ordinary filtration that show-finned bettas resent. Put the saved effort into her water instead: the 24–28 °C band on her record is tighter than most of our bettas, so a thermometer check should join your feeding routine. The 40-litre minimum gives her genuine swimming distance, which an active plakat female uses far more visibly than a heavy-finned male would. Feed her carnivore fare, expect her at the surface by week one, and treat any territorial posturing as the normal species behaviour her record describes rather than a problem to fix.

    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
