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
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.
Cycle and heat the 40-litre tank first; greens show their best colour only in stable water. Shipped across the UK by licensed live-animal courier with our live arrival guarantee.
