Blue Rim Halfmoon Plakat (Betta Splendens)
These fish display a pale or white body with a striking blue edge outlining the fins. As with other marble-influenced patterns, the colouring can continue to shift or develop further blue markings as the fish ages.
As a halfmoon plakat, this male combines the full 180 degree tail spread of the halfmoon with the shorter fins of a plakat, giving a broad, fan-like tail on a stockier, more robust body. The shorter finnage traces back to the fighting bettas historically bred across Southeast Asia, making this variety a hardy, agile swimmer.
Juveniles often don't display full colouration and become more and more vivid as they age, making them fascinating to watch as they change.
