Betta spl. female Halfmoon White - Betta Fish for Sale UK

All-white bettas divide opinion until people see one in the flesh — then the argument usually ends. This Halfmoon White female carries the type's broad tail spread in clean, unmarked white across her 6 cm frame, a colourway that turns crisp and luminous over dark substrate and makes every movement easy to follow. For aquascapers working in greens and shadows, she is the obvious accent fish.

Moderate care and a semi-aggressive temperament define the keeping plan. Snails are her safest companions; peaceful shrimp may hold their own in larger, well-planted tanks though hunting happens; and carefully selected peaceful bottom-dwellers are possible in bigger aquariums, added with caution. Her avoid list mirrors the species standard — male bettas, fin-nippers such as tiger barbs, aggressive or highly territorial fish, large predators, and fast boisterous species that wear her down. She settles from 20 litres upward, with the full 24–30 °C band available, pH 6.0–7.5 and hardness 1–15 dGH. Expect her stationed in the top third of the tank, and expect occasional territorial flashes — they pass, but they are part of owning any Betta splendens.

Plan her tank like a photographer and keep her like a pragmatist. Dark substrate, green planting and side lighting make an all-white fish luminous; the husbandry behind the image is plain — 20 litres or more, heater anywhere in the wide 24–30 °C band, carnivore feeding, weekly changes inside pH 6.0–7.5 and 1–15 dGH. White finnage doubles as a condition report, showing stress or water decline before most keepers would otherwise notice, so glance at fin edges at every feed. If you attempt the cautious bottom-dweller company her record allows in larger tanks, watch the opening days closely and have a fallback plan. Most owners conclude she carries the aquarium better alone.
