Betta spl. male halfmoon big ears - Betta Fish for Sale UK

Watch a big ear halfmoon swim and the pectorals steal the show: enlarged, rounded fins either side of the head — the dumbo trait — beating constantly beneath the main event of a full halfmoon tail. This male runs to about 7 cm, and the doubled spectacle of spread caudal plus fanning pectorals gives him a presence few single-trait bettas match.

Unusually for an aggressive-rated male, his compatibility record lists named community options: Corydoras catfish, Otocinclus, small peaceful rasboras, snails and some peaceful shrimp species — all with caution, all in suitably large tanks, and all chosen because they neither resemble bettas nor nip fins. The exclusions hold the line: other male bettas, fin-nippers, aggressive cichlids, large predators, brightly coloured or long-finned fish, and specifically guppies, whose flowing tails trigger him. Moderate care covers his needs: 38 litres minimum, 24–30 °C, pH 6–7.5, hardness 1–15 dGH, carnivore feeding, calm surface water in the top region he holds. Territorial behaviour intensifies toward breeding condition, so monitor any community closely in the first weeks.

A community around this male succeeds on selection discipline. His record's named companions — Corydoras, Otocinclus, small peaceful rasboras — share a logic: bottom and mid-water species, drab beside him, with no trailing fins to trigger his instincts. Stay inside that logic and the 38-litre tank works; deviate toward anything guppy-shaped and it will not. Feed him at the surface while the catfish work below, keep temperature steady in the 24–30 °C band, and hold pH 6–7.5 with weekly changes. The big-ear pectorals make him absurdly watchable in open water, which is one more reason the community format suits him: he displays more when there is gentle activity below his territory than he ever does alone.
