I'm trying to place an order on the website for some medication. I need to treat both Gill flukes and internal worms. I just received some Guppies and zebra danios. The Danios have flared gills and the Guppies are looking kind of skinny. Stringy poop. I tried watching videos on thier YouTube channel but I'm undecided what to get, what should I order? Guppies and danios are in separate aquariums. Guppies are in a 10 gallon and danios are in a 29 gallon. If that helps in knowing how much I need to treat
