Key Features:

Distinctive Appearance:
A mixed form of the Siamese fighting fish featuring traits of both Halfmoon and Plakat types. It typically shows a more muscular, short-finned Plakat body with broader, more flowing fins than a pure Plakat, sometimes approaching a Halfmoon-style tail spread. Coloration varies widely, often with rich reds, blues, greens, or marble patterns depending on the individual line.

Behavior & Personality:
A bold, active, and highly territorial fish, especially males. Compared to long-finned varieties, this mix is often more agile and energetic due to its shorter fins. It displays strong flaring behavior and can be quite interactive with its surroundings and keeper.

Care Requirements:

Tank Conditions:
Requires a heated, stable aquarium with gentle filtration and minimal current. Ideal temperature range is 76–82°F (24–28°C). Prefers soft to moderately hard water with a slightly acidic to neutral pH (6.5–7.5). A well-planted tank with resting spots and surface cover is ideal.

Diet:
Carnivorous/omnivorous. Should be fed high-quality betta pellets as a staple, supplemented with frozen or live foods such as bloodworms, brine shrimp, and daphnia. A protein-rich diet helps support coloration and activity levels.

Compatibility:
Males must be kept alone due to high territorial aggression. In community setups, only peaceful, non-fin-nipping species are suitable, and even then careful monitoring is required. Not compatible with other male bettas.

Size and Growth:

Adult Size:
Typically reaches 2.5–3 inches (6–7.5 cm) in body length.

Growth Rate:
Moderate growth, reaching full size and coloration within several months under stable, well-maintained conditions.

Overview:

Betta splendens Halfmoon Plakat Mix is a selectively bred ornamental betta variant valued for combining the strength and agility of Plakat types with the enhanced finnage of Halfmoon lines. It is well-suited for beginner to intermediate aquarists who can provide stable warm water conditions and solitary housing for males.
