Betta spl. female SuperDelta blue - Betta Fish for Sale UK

Here is a female betta that keeps things straightforward: the blue SuperDelta combines a wide, near-halfmoon tail with an easy care rating, making her one of the simplest show-finned bettas in our range to keep well. Expect a fish of around 6 cm dressed in blue from body to fin edge, displaying that broad SuperDelta spread whenever something catches her interest.

Easy refers to husbandry, not to unlimited sociability. Recorded as semi-aggressive, she takes the standard betta precautions: snails make safe tank mates, peaceful shrimp may coexist in larger planted tanks though they may be eaten, and beyond that her company should be chosen against the avoid list — no other bettas, no fin-nippers, no aggressive cichlids, no large predators, and no fast boisterous species that turn mealtimes into a race she loses. Her housing needs are modest and specific: 25 litres minimum, temperature anywhere across the wide 24–30 °C band, pH 6.0–7.5, hardness 1–15 dGH. She holds to the upper levels of the tank, and territorial behaviour can emerge around breeding condition — normal for the species and short-lived if no trigger remains.

Her wide 24–30 °C tolerance has a practical meaning: room placement matters less, summer heatwaves threaten less, and a basic heater does the job a premium one does for fussier fish. That forgiving streak runs through her whole care sheet — easy rating, standard carnivore feeding, weekly changes inside pH 6.0–7.5 and 1–15 dGH, a manageable 25-litre minimum. What she shares with every betta is the social fine print: her semi-aggressive grading is dormant most of the time and visible occasionally, especially toward breeding condition, so any permitted tank mates should be established before she arrives. For a first show-finned fish, the combination of broad tail and broad tolerances is hard to argue with.
