cannot see anything on blackspot and its life cycle, i wonder if there is anything in depth written about this, leebca do you know anything about this disease?

Not exactly sure what it is you are referring to. Are you taking about what we call Black Ich?

Black Ich is actually a group of organisms that have similar characteristics. They burrow into the fish. They are so small that they are invisible to the unaided eye. However, when they take nutrients from the fish, they cause some hemorrhaging of blood. We then see the tiny black spots of these sites.

This is a reference and a link in that reference to a photo of a fish with Black Ich: http://www.petsforum.com/personal/tr.../blackich.html

If this isn't what you are referring to (because there are other conditions that cause blackened areas and similar symptoms), let me know and perhaps provide some photos of what it is you're looking at.
