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.

Three colours on one fish — that is the promise of the rose tricolor, a rose-finned male Betta splendens whose body and finnage layer three distinct shades into a single moving display. At roughly 6.5 cm with full rose-type finnage, he is bred purely for visual impact, and in a softly lit planted aquarium the layered colouring shifts as he turns through the light.
He carries a moderate care rating and an aggressive temperament, which between them define his housing. Plan for a dedicated setup: peaceful snails work, some peaceful shrimp can persist in heavily planted tanks though they may be hunted, and that is broadly where the guest list ends. The record specifically warns against other male bettas, fin-nipping species, aggressive or highly active fish, long-finned tank mates, small fish that could be mistaken for prey, and most shrimp and very small invertebrates. He is a top-region fish, so floating cover and surface calm matter more to him than bottom decor. Water-wise he asks for 24–30 °C, pH 6.0–7.5, hardness between 1 and 15 dGH, and a tank of 20 litres upward — small enough for a desk, big enough to be stable.
Getting the best from layered colour is a lighting exercise as much as a husbandry one. Side-on viewing under warm-spectrum light separates the three shades most clearly, while overhead-only lighting flattens them — worth knowing before you position the tank. Husbandry itself is routine: carnivore feeding, a heater holding any point in the 24–30 °C range, and weekly changes keeping pH inside 6.0–7.5 and hardness in the 1–15 dGH band. The 20-litre minimum suits a desk or counter setup, though more volume always steadies chemistry. Rose-finned males carry extra fin material, so follow the same gentle-flow rule as other heavy-finned strains and give him a resting point near the surface he favours.
Tricolor combinations vary fish to fish, so expect your male's three shades to be his own rather than a copy of an image online. He can grow territorial when breeding. Every UK order travels with a licensed live-animal courier under our live arrival guarantee.
