I import a fair number of monster fish to Canada, with a focus on Asian arowana. I think the SB craze is mostly driven by the breeders in Thailand/Malaysia/Indonesia. In general, novelty drives the fish hobby in Asia and maybe elsewhere. Breeders are constantly trying to come out with something "new" or "different' to appeal to consumers. While I appreciate some of the new albino and leucastic forms of fish coming to market, I am no fan of the SB craze. I especially do not like SB arowana or the hunch back variety of reds. The spinal curvature is a deformity in my opinion. But to each their own I guess.
