My fish don't have ich or anything else, and they still do it on occasion.
I would watch them closely first. Then think about treatment options if you think there is a problem.
^^^^True that five minutes before is better than five minutes later....You know your fish and it sounds like this is a little out of the normal for them? am I right?
Yeah just a bit. I have one that will flash from time to time and I don't worry about him. But is is a new one that is doing it right now. May I'm just over protective, but...
You know.
