Ich

Hi

Unfortuantly i have some ich on my new cardinals i added few days ago.

I'm not sure what treatment i should use as i havent encounted an ich outbreak before.

My tank houses cherry shrimps, amano shrimps, ottos and cardinals. with a carpet of hairgrass eleocharis acc. so i know the medication should not contain copper.

I do not have an extra tank to move my shrimp so unfortuantly they'd have to stay in the tank during the medication time.

my tanks temperature is currently at 79f/23c

theres only afew cardinals that are infected, approximately 5 of them with 1-3 white spots on them. Is it an absolute must that medication is required? I remember seeing few dots on new added cardinals but it only lasted 2-3 days then gone for a month, till i added the new fish 3 days ago. (i do understand although when parasite is not attached to a host it can still be alive at the bottom of the tank)

Well the bottom line is what are your experiences and what works?

Thank you
