Betta spl. male plakat halfmoon yellow - Betta Fish for Sale UK

Take the plakat's short, practical finnage, breed the tail to open at the halfmoon's full angle, and finish the whole fish in bright yellow: that is the halfmoon plakat yellow, a 6 cm male combining the agility of a short-finned betta with show-grade tail geometry. The colour does him favours too — yellow holds its visibility in planted tanks where darker fish disappear.

This is an easy-care strain with an aggressive streak, so the work is in stocking decisions rather than maintenance. His record allows peaceful snails reliably, peaceful shrimp with caution and acceptance of individual variation, and calm non-nippy community fish only in larger, heavily planted tanks where each fish's temperament has been considered. It firmly excludes other male bettas, fin-nippers such as tiger barbs, aggressive or territorial species, brightly coloured long-finned fish that he reads as rivals, and small fish he might mistake for prey. From 20 litres he is content, with water between 24 and 30 °C, pH 6.0–7.5 and hardness 1–15 dGH. As a short-finned male he is quick and constantly visible in the upper water; breeding condition raises his territorial drive.

Short fins plus an easy rating make him close to maintenance-proof: no tail to protect from flow, no fragile rays, just a fast yellow fish using all of the 20-plus litres you give him. His carnivore appetite is brisk and his metabolism matches it, so feed consistently and skip the temptation to compensate with volume — small and regular wins. Hold the heater anywhere inside 24–30 °C, keep pH between 6.0 and 7.5, and his three recorded years should pass without an emergency. The halfmoon-angle tail still appreciates an occasional flare trigger; a brief mirror session lets him display the full spread the strain is bred for without a rival ever entering his water.
