Betta spl. male SuperDelta green - Betta Fish for Sale UK

For keepers chasing green — and many do, for years — the SuperDelta male is the practical way in. He carries the elusive green colouring across a broad SuperDelta tail on a 7 cm body, with a pH tolerance of 6 to 8 recorded against his name: wide enough to take hard or soft UK tap water in stride, which removes the chemistry tinkering some imported strains demand.

The trade-off is temperament. He is rated aggressive, and his approved company is short: small peaceful snails, and some peaceful shrimp species that may nonetheless be eaten. Avoid other male bettas absolutely, then fin-nipping fish, aggressive or highly active species, large predators, and — a specific entry on this record — species that require cooler water, since his 24–30 °C requirement is non-negotiable year-round. He needs a 40-litre minimum, larger than many bettas, plus hardness between 1 and 15 dGH and a carnivore diet. The top of the tank is his domain; furnish it with surface cover, keep flow gentle for the broad tail, and expect firmer territorial behaviour if he approaches breeding condition. Care level: moderate.

His two standout numbers — pH tolerance to 8 and a 40-litre minimum — define the setup. The first means London-hard tap water needs no softening campaign; the second means he gets more room than most males in our range, which his activity level justifies. Within that space, follow the heavy-fin protocol: outflow baffled to a ripple, resting structure near the surface, smooth decor only. Feed his carnivore diet with variety to keep the green iridescence dense, and pin the heater anywhere inside 24–30 °C — his record's cooler-water warning cuts both ways, ruling out unheated rooms entirely. Greens this size hold their value to a keeper for years; treat the initial setup cost accordingly.
