If its on one fish in the tank, you need to treat the entire tank. There is no point in quarantining this fish. The white spots only appear at the end of the parasite's life cycle. The parasite literally falls off of the skin and fins of the fish, causing the white spots, and it falls and lands on the substrate. In the substrate it reproduces and waits for another fish to swim by to infect. Newly infected fish will not show white spots. You won't know a fish is infected until they're contagious, which is at the end of the parasite's life cycle when it causes the white spots.
You can treat this one of two ways: heat and salt, or medication.
Which method is best for your tank depends on what other fish live in the tank.
What fish species live in this tank? And how big is the tank?
I'm doing same thing you did and on beginning of week 2 today.. were yours glofish? did ich stay gone for you after turned temp back down?Zorse said:Well it's been 2 weeks today and all the fish are looking great! The ones that had Ich lost some of their fins, but they have already grown back and there are no more spots on the fish. Starting to lower the water temp and will do a big water change today. They all look so happy! Was such an easy way to treat and I think I'm lucky that it was a small case.
