I noticed the Ich on my tangs Monday afternoon and proceeded to monitor my tank. I couldn't see Ich on any of my other fish. My tangs didn't stay still enough for me to get a good picture of them, mostly the Ich was on their fins and face. But two of the less dominant ones had Ich all over. I watched closely all afternoon until lights out. When all that was left was the blue LED's I saw more Ich. My wrasses were covered in it. I couldn't see the Ich under normal light but under the blues was a different story.
