Feeding High Quality Pellets Only Vs Live Feeds Supplements Options

[Donny041280]

Hello guys,
my ranchu kenna flukes recently and many times before, maybe(or 100% sure!!?) due to my supplemental frozen bloodworm (FBW) feeding ( i feed 4 times hikari lionhead and 3 times FBW), in my area the FBW are always risky(many yellow worm) and after searching for so long there are no quality fbw here.. give up lah

Ok
My question is...
1.if we feed only on high quality pellets like hikari lionhead or saki only could we achieve the same growth effect with feeding live feed? (frequent pellet feed 7/8 x a day)
2.if we use monthly basis of flukes medicine will it harm our ranchu? Ex: super disease away from ocean free (PP) it works wonderfull but reading the post the risk is very high, i have tried salt 2% doesnt work and no prazi here..
3.just to make sure that if we feed pellets only our fish will 99.999% free of parasites right?

Ok then thats all, just so tired of medicating sick fish, lots of water change and praying

Thx bos!
