The arrival of the giant betta was a result of hard work and careful selection of breeders. In 1999 Athapon developed the first giant plakat by size selection of green fighter plakats, the goal being bettas that reached a length of at least 3 inches. His reason for using green was his observation that this color, in particular, was larger in size on average than other colors. It took approximately 5 generations to produce the first 3+ inch long bettas, and the spawn yielded about 20% very large bettas who later developed into 'giants'. After several years of research and work on his giants, Athapon started developing other colors and fin forms, including blue, yellow, white, red, and green.

The Giant has been crossbred and is a genetically dominant trait, so more than 50% of your fry will be giants, if not all. Some IBC members have formed a set of rules for Giants, these include:

1) The Giant trait is determined by one set of genes
2)The mutated Giant gene is incompletley dominant over the regular sized gene.
3) If an offspring carries both 'Giant' genes it will show the full-sized Giant trait.
4) If an offspring carries only one 'Giant' gene it will show Half-Giant size.
5) If an offspring does not carry any 'Giant' genes it will be regular size.

Unfortunately, most of the fish now advertised as "giants" are not true giants but half giants.
