The betta fish is one of the most popular and most misunderstood freshwater species. This guide covers everything from proper tank size to the truth about tank mates.
Maintain these water conditions for optimal health and vibrant colors
Female bettas with show-grade finnage are still underrated, and this SuperDelta big ears mix makes the case for them. Each fish combines two ornamental traits — the broad, near-halfmoon SuperDelta tail and the oversized dumbo-style pectoral fins known as big ears — in a mixed colourway, on a female frame of around 6.5 cm. The pectorals move constantly as she swims, which gives the whole fish an animated quality males with heavier finnage often lack.
Here is the practical advantage: her compatibility record is the most flexible in our betta range. Alongside snails and peaceful shrimp in heavily planted tanks, she is listed as compatible with peaceful small schooling fish and small non-nippy community species — a genuine community-tank candidate, where males of this species rarely are. Limits remain: keep her away from other bettas, fin-nipping fish, aggressive cichlids, large predators, and species needing very different water. She is semi-aggressive, moderate care, and can turn territorial, so watch new introductions. Provide 20 litres minimum (more in a community), 24–30 °C, pH 6.0–7.5 and 1–15 dGH; she favours the upper water.
If you do build the community her record uniquely allows, sequence it properly: established peaceful schooling fish first, bottom-dwellers settled, and her as the final addition to a planted, structured tank of comfortably more than her 20-litre solo minimum. The big-ear pectorals make her easy to track during the critical first days — if they are fanning steadily and she feeds from the surface, integration is working. Solo keepers have it even simpler: 24–30 °C on the heater, carnivore feeding, pH inside 6.0–7.5, done. Either way her three-year lifespan plays out best with stable chemistry, and her mixed colourway means her finnage — not a particular shade — is what you are curating for.
Supplied as a colour mix, so finnage traits are guaranteed while the shade is the luck of the draw — mixes from this line span the full betta palette. Despatch is by licensed live-animal courier with our live arrival guarantee on every UK order.
