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
Rose-type finnage in cool blue gives this male a layered, petalled look — the rose line's abundant, overlapping fin material rendered in a single blue palette across a fish of around 6.5 cm. Where many show strains chase contrast, the rose blue goes the other way: one colour, maximum volume of finnage, and the result moves through the water like fabric.
His ratings make an interesting pair: easy care, aggressive temperament. Daily upkeep is genuinely simple — stable warmth, clean water, carnivore feeding — but his social rules are strict fighter's rules. Peaceful snails are sound companions, peaceful shrimp only with caution in heavily planted tanks, and very calm non-nippy fish are conceivable only in larger aquariums, watched closely. Keep him from other male bettas, fin-nipping species such as tiger barbs, aggressive or territorial fish, large predators, and brightly coloured tank mates that draw his fire. The recorded floor is 20 litres at 24–28 °C — a slightly tighter heat band than most of our lines, worth noting when you set the thermostat — with pH 6.0–7.5 and hardness 1–15 dGH. A surface-oriented fish, more territorial when breeding.
Note the thermostat detail before anything else: his band is 24–28 °C, not the wider range many of our bettas carry, so set the heater mid-band at 26 °C and let it hold. The rest of his easy rating is genuine — carnivore feeding, ordinary weekly maintenance inside pH 6.0–7.5, and a 20-litre minimum that suits compact setups. Rose-type finnage benefits from the same surface-resting furniture as other heavy-finned strains, and his all-blue colouring rewards a pale substrate that bounces light up through the fin layers. If you trial the very calm tank mates his record cautiously permits, do it in a larger tank than his minimum and watch the first 48 hours closely.
All that rose finnage is heavy to carry, so furnish the upper tank with resting points and keep flow soft. Your fish leaves us with a licensed live-animal courier and arrives under our live arrival guarantee, anywhere in the UK.
