Ich has a 6 week cycle. its not been that long yet has it? id give it a little more time before adding an fish back. and when you do ad fish. use a QT tank to make sure those DONT have any ICH as well. or youll be right back to where you are now. do you have a QT tank now? if so u cld get a fish now and by the time the 6 week time frame on your display tank is over. you cld probably ad the fish from Qt into it.
I'm not an expert so get some other feedback before doing anything i suggest lol
anyone else have ideas, comments?
just dont rush anything. and that you can be sure of!
