Hmmm, as what Galactuz said, worm is good for growth but they carry bacteria... My point here is Mr. Lai fish might be carrier for bacteria or virus because it was fed with Tubi worm... Bacteria or virus carrier won't show any sign if they are in 'Good' condition. But when environment changed suddenly, fishes become weak and immune power down, and these bacteria or virus carry by the carrier will come out and do bad thing...
