Haha some correction to be made here.

Sifu Ng no doubt has a lot of purer/better strain of guppies but a show class??? I doubt any of us here has a show class quality guppies

The nearest place to get show quality is most probably Singapore (not that I promoting though). But sad to say lah.... A show quality class guppy will set you back for few hundred ringgit. So are you willing to pay the 1st question you might ask yourself.

Squareballs if you put your grass on mosaic on show I doubt you'll even get classified i.e not even judged hehehehe
