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
At a recorded 11 cm, the Betta paradise outgrows every Betta splendens strain we stock — this is the heavyweight of our labyrinth fish section, supplied in mixed colours with each fish wearing its own combination. Size changes everything about the keeping experience: more presence, more appetite, and a fish that reads clearly from across the room rather than up against the glass.
Despite the bulk he carries an easy care rating and a semi-aggressive temperament, though his record frames company carefully: best kept alone, or with robust, similarly sized peaceful fish in a larger tank — and snails. The exclusions acknowledge what he is: no other male bettas, no fin-nipping fish, no large aggressive species, no fast boisterous tank mates, and notably no other labyrinth fish of similar shape or temperament, which his instincts treat as rivals. The recorded minimum of 40 litres should be considered a true floor for an 11 cm fish. Water sits at 24–30 °C, pH 6.0–7.5, hardness 1–15 dGH; he is a carnivore — portion for his size — and occupies the top region of the aquarium. Territoriality rises around breeding condition.
An 11 cm labyrinth fish rewrites a few betta habits. Feed substantial carnivore portions — his intake is a different order from a splendens — and expect him to dominate the surface at mealtimes with real confidence. His easy rating holds because the requirements are ordinary even if the scale is not: heater anywhere in 24–30 °C, pH 6.0–7.5, hardness 1–15 dGH, weekly changes sized to his volume. If you attempt the robust, similarly sized peaceful company his record allows, the tank must grow well past the 40-litre floor, and his ban on similar labyrinth fish stays absolute regardless of size. Most owners keep him as the single spectacular resident of a tank built around his bulk.
If standard bettas have started feeling small, this is the natural next step without changing water chemistry or habits. Mixed-colour stock, shipped UK-wide by licensed live-animal courier with live arrival guaranteed.
