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

Butterfly patterning splits each fin into bands — colour at the body fading or switching to a contrasting outer band toward the edge — and on a SuperDelta male the broad, near-halfmoon tail gives those bands maximum room to read. This is a 7 cm fish whose fins look deliberately designed, the banding tracing the sweep of the SuperDelta spread every time he turns.

The record pairs moderate care with a semi-aggressive temperament and an unusually wide pH tolerance of 6 to 8 — about as adaptable to UK water chemistry as Betta splendens gets. Housing guidance starts at best kept alone: if company is attempted, only very peaceful, non-nippy species in a larger, heavily planted tank, with small snails acceptable and shrimp or small fish at risk of being eaten or stressed. Excluded are other male bettas, fin-nippers such as tiger barbs, aggressive or highly territorial fish, large predators, and fast boisterous tank mates that outcompete him. He needs 20 litres minimum at 24–28 °C with hardness 1–15 dGH, eats as a carnivore, holds the top region of the tank, and turns more territorial when breeding condition develops.

That 6–8 pH window is the standout figure on his record — wide enough that hard-water keepers who normally pre-treat for bettas can skip the chemistry entirely and concentrate on the two things butterfly males actually need: stable warmth in the 24–28 °C band and calm water for the banded finnage. Feed a varied carnivore diet to keep the band contrast sharp; the boundary between inner and outer fin colour blurs first when condition drops, which makes it a useful weekly checkpoint. House him in 20 litres or more with surface resting spots, snails as default company, and the record's heavily-planted-tank condition met before any cautious experiment with tank mates begins.
