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

Mustard colouring meets the SuperDelta tail in this 7 cm male — the strain's dark body running into yellow-toned finnage, displayed on a tail that opens broad and just short of a full half-circle. Of the mustard-type bettas we list, the SuperDelta version offers the most fin area for the colour gradient to play across without the fragility of the largest show tails.

One detail sets his record apart from nearly every betta on our books: his diet is logged as insectivore rather than general carnivore, so build his feeding around insect-based foods — the protein source the strain is recorded to need. Socially he is an aggressive male with conventional restrictions: best kept alone, peaceful snails acceptable, peaceful shrimp possible in larger well-planted tanks though they may be eaten. Exclude other male bettas, fin-nippers, aggressive or highly territorial fish, large predators, and bright or long-finned tank mates. House him in 38 litres minimum at 24–30 °C, pH 6.0–7.5, hardness 1–15 dGH; he occupies the top region and his territorial instinct rises toward breeding condition. Care overall is moderate.

The insectivore note rewrites his shopping list before he arrives: bloodworm, daphnia, mosquito-larvae-based foods and insect-meal pellets should anchor the rotation, with generic fish-protein flake demoted to filler at most. Watch how the mustard gradient responds over the first month — insect-led feeding visibly deepens the body-to-fin transition on this strain. Beyond the menu, he keeps like any large SuperDelta male: 38 litres minimum, gentle flow, surface resting points, heater fixed inside 24–30 °C, water held at pH 6.0–7.5 and 1–15 dGH. His aggressive grading keeps the tank his alone bar snails. Get the diet right and everything else about him is repaid in colour.
