Red Koi Galaxy Halfmoon Plakat Male Betta 4cm

The Red Koi Galaxy Halfmoon Plakat (Betta splendens) is a highly sought-after variety, combining the bold red and white koi patterning with a galaxy-style iridescent scale overlay. The Halfmoon Plakat (HMPK) tail form offers the full 180° spread of a Halfmoon with the shorter, stronger fins of a Plakat — making for a striking and active display fish.
