So yesterday I noticed that one of my clown loaches had ich. And over the course of my fish keeping days I have battled Ich successfully (mostly with loaches) about 4-5 times with a combination of Temp increase and ich medicine that turns my water blue. But yesturday I did not have any medicine nor means to get to a LFS until monday. So I cranked the Temp up to 90º at around 7:30 am and this morning and 10 am ICH IS GONE!!! I am very happy, and so are my loaches.
