After a recent, nasty battle with Ich, I have told myself that I will always assume the worst from henceforth.
As to your fish having spots in the morning, none at night....I recently learned this is indeed the normal cycle for Ich. The cysts will release at various times during the day, but have a great tendency to actually burrow on your fish during the evening hours. This is why you see the spots in the morning. The eggs on your bedrock release during the evening, attach, and start forming their cysts on your fish. During the day they release and repeat their cycle that night.
From what I've read, this is due to little fish inactivity at night, fish laying on the floor, etc. Basically it's just easier for the little suckers to attach when the fish is right there when they hatch and not moving.
As to treatment, I basically did exactly what Steve suggested..except I didn't use a QT
tank. Having the tank I do with an aggressive trigger I wasn't too worried about throwing Copper in there, and let me tell you Hyposalin + CopperSafe = dead ich. With your fish though, don't know how well they stand up to copper. Good luck to you.
