A nasty intestinal parasite got into one of my guppy tanks (the only symptoms were white/stringy poop, loss of apetite and death, so I couldn't narrow it down further than 'intestinal parasite'), and wiped out all my guppies but four males and a handful of fry.
It's been a few weeks since my last guppy died, and I want to try moving the survivers into another tank with my other guppies (the survivers are by far my prettiest males, and I don't want them or their fry to go to waste). I also have a chinese algea eater and some cherry shrimp in there that I want to move as well.
So, how can I do this without moving the parasite into my new tank? I have a hospital tank I could use to quarantine and treat each species at a time, but I don't know how long they should stay in there or what to treat them with.
