I know it doesn't look that much different and I'm no expert but the top photos look like gorgeous coraline and the last looks like horrible cyano very subtle differences in these pics but the coraline doesn't grow so uniform like cyano as it spreads more like a grass and coraline will pop up in spots all over the tank please correct me if I'm wrong

Cyano easily blows off surfaces, sometimes you can see air bubbles forming or trapped within larger blankets, that is coralline.

This, if it blows off easy with a baster it's cyano.
