Betta (Siamese Fighting Fish) – Premium Koi Delta Tail – MALE

Koi Delta Tail Male – Koi Patterns with Wide Triangular Delta Fins!

Koi Delta Tail Male arrives with classic koi-inspired colour mixes of red, white, black, and orange that spread across his body and wide super delta tail fins, which flare into a triangular shape. Hand-picked from imported stock by our betta specialists, this male combines vibrant random patterns with sturdy plakat form. Aquarists select him for his bold contrast and composed nature. Steady care keeps his koi colours sharp and delta tail balanced.

Size and Lifespan

This male currently measures around 5 cm in body length. He grows steadily with balanced nutrition and stable water. Adults typically reach a maximum size of 7 cm. With consistent maintenance, including regular water changes, these bettas commonly live 3 to 4 years.

Ideal Tank Setup

Arrange a calm, low-flow aquarium so the Koi Delta Tail Male can settle comfortably and behave naturally. These fish prefer gentle circulation and plenty of cover. Install an air-powered sponge filter to maintain soft turnover. Secure the lid tightly and leave an air gap at the surface for breathing. This setup supports his wide delta fins and reduces stress.

To replicate its natural habitat:

• Plant dense stem clusters with floating cover to create shaded resting zones.
• Attach Java fern or Anubias to driftwood for mid-level structure and perching spots.
• Position small clay pots or short tube sections as secure retreats.
• Add dried Indian almond leaves to release tannins and encourage microbes.
• Use a smooth dark substrate to mimic shallow Thai vegetated waters.

Compatible Tank Mates

This male usually thrives best alone to protect his broad super delta tail from damage. In larger, well-planted tanks, he can accept very calm companions that avoid his space. Avoid fin-nippers or active fish that cause stress. Dense planting and visual barriers help maintain peace.

Suitable tank mates include:

• Tiny peaceful schoolers like galaxy rasboras or ember tetras.
• Shy bottom-dwellers such as pygmy Corydoras or small Kuhli loaches.
• Non-competitive snails or gentle shrimp that stay discreet.
• Other slow-moving mild community fish.

Diet and Feeding

Offer the Koi Delta Tail Male a varied omnivore diet to support his koi colour mix and fin condition. Use premium sinking betta pellets as the daily staple. Supplement regularly with frozen or live foods like bloodworms, daphnia, and brine shrimp. Feed small portions once or twice daily. Remove uneaten food promptly to preserve water quality.

Breeding and Behaviour of Koi Delta Tail Male

Males build bubble nests at the surface using plant material when breeding conditions align. He courts females with displays and guards eggs diligently after spawning. This fish shows typical betta territorial behaviour, especially toward other males. Provide ample hiding places to encourage natural instincts while minimising conflict risks.
