Betta spl. male Imbellis red tail - Betta Fish for Sale UK

Keepers who want imbellis blood with a bolder finish should meet this red tail male. The strain takes the wild imbellis body plan and signs it off with a wash of red through the tail — a simple, striking accent that reads beautifully against dark substrate and dense planting. He is a top-of-the-tank fish with a carnivore's diet, growing to around 6.5 cm and typically living about three years, which makes him a manageable, characterful centrepiece for anyone stepping beyond standard community stock into wild-line bettas.

Temperament sits firmly in semi-aggressive territory, and the usual betta arithmetic applies: one male per tank, no exceptions. The compatibility record for this strain favours quiet company. Peaceful snails are the safest companions; peaceful shrimp may work in larger, well-planted aquariums; and very peaceful small fish can share space only in bigger, heavily planted setups — even then with caution. Avoid other male imbellis, fast or boisterous tankmates, large predatory fish, fin-nippers, and long-finned species whose trailing fins may trigger aggression. Expect heightened territoriality if he comes into breeding condition, and plan the aquascape accordingly.

Water requirements are undemanding for a moderately experienced keeper: temperatures from 24 to 28 °C, pH between 6.0 and 7.5, and soft to moderately hard water in the 1–10 dGH band. A minimum of 20 litres gives him room to patrol the surface, though extra volume always widens your tankmate options. Build meals around protein-rich foods sized for a fish of 6.5 cm, offered up top where he actually hunts.

Before you order

This listing is for a male, so build your stocking plan around a single-betta showpiece rather than a pair or group. He suits a planted nano on his own, or a carefully assembled low-key community in something larger. If you are matching water for the first time, aim for the middle of the recorded ranges and let the tank run steady before he arrives. Dispatch to UK addresses is handled by a licensed live-animal courier, with our live arrival guarantee on every order.
