Anyone building a collection around wild-type bettas eventually wants females, and this wild imbellis yellow tail female fills that gap nicely. She shows the line's yellow tail colouring on a wild imbellis body, and her care record is specific about what suits her: warm, planted, low-flow water where her colour and confidence both come forward. Adult size is about 6.5 cm with a typical lifespan of three years, and she patrols the upper levels of the aquarium, taking her food at the surface as a true top-region carnivore.

Her tankmate options run broader than a male's. Small rasboras, peaceful snails and small peaceful fish that will not nip fins all make suitable company, and peaceful shrimp can be attempted provided she shows no predatory interest in them. Keep her away from fin-nipping species, fast boisterous fish, large aggressive or predatory tankmates, and any male imbellis — aggressive bettas of either sex are also on the avoid list. Though classed semi-aggressive, the record's caution is simpler in practice: she can hold territory, so plant densely and break up the sightlines before she moves in rather than after the first squabble.

Recommended water sits at 24–28 °C with pH 6.0–7.5 and a soft 1–10 dGH. The suggested minimum tank is a roomy 60 litres — which conveniently leaves space for a shoal of those rasbora companions — and the moderate care rating puts her well within reach of anyone who tests their water and keeps temperatures steady through the year.

Who she suits

Choose this female for a planted community of small peaceful fish, or to balance out a wild-betta project that already has its male.

She travels to UK addresses with a licensed live-animal courier and is covered by our live arrival guarantee from door to door.

    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
