Betta spl. male crowntail bicolor - Betta Fish for Sale UK

Two colours, one crown. The bicolor crowntail male wears a contrasting body-and-fin combination across the strain's trademark spiked rays — body in one shade, the crown of separated fin tines in another — so every flare doubles as a colour-block display. At about 6.5 cm and with an easy care rating, he is one of the more approachable routes into crowntail keeping that we stock.

The temperament file says semi-aggressive, and the housing recommendation opens with two words: best alone. Small non-aggressive snails join safely; shrimp are possible in heavily planted tanks but are often preyed upon, so add them as calculated risk rather than expectation. Excluded company runs to other male bettas, fin-nipping fish, aggressive or highly territorial species, large predators, and fast boisterous tank mates that grind a betta down with constant motion. He needs at least 40 litres — more generous than many betta minimums, and his rays will thank you for low-turbulence filtration within it. Hold the water at 24–30 °C, pH 6.0–7.5, hardness 1–15 dGH. Like the rest of his species he favours the top of the aquarium and turns more territorial in breeding condition.

An easy-care crowntail is not a contradiction — it is this listing's whole point. The bicolor line tolerates the full 24–30 °C band, sits happily across 1–15 dGH, and feeds without fuss on standard carnivore fare, leaving the crown rays as the only part of his keeping that demands actual delicacy. Gentle flow and smooth decor protect them; everything else is weekly routine. His 40 litres should be planned with the surface in mind, since that is where he holds station, and the two-colour contrast means you will notice immediately if condition slips — the boundary between his shades is your sharpest health indicator. Three years is the standard expectation, often exceeded with boring, consistent care.
