that's been my experience. it leads me to the conclusion that their size is not a result of the traditional "giant" gene as true giants and half-giants are more often than not a lot MORE aggressive that a typical splendens. as for people thinking they're crossbred with imbellis, i think that just comes from the fact that when they originally came out they were only available in a wild-type coloration, which some people mistook, along with their relative docility for imbellis traits. the fact of the matter is that most petco kings are not metallic like imbellis are, and a crossbreed between the species would most likely yield a smaller
fish rather than a ginormous one. the king-imbellis hypothesis is just idle speculation.
that said, i've never seen a female for sale, but i wonder if they're referred to by the breeders as "Queen Bettas."
