Algae or something?

I noticed today while looking at my tank that there was this weird spot of what I guess is cyano algae on the back of my glass.
the only thing is, is that is looks quite weird in my opinion.
It is very thick and looks to have almost flowery spots
i know this isn't the best description and these pictures are blurry but does anyone know if this is just plain old cyano or something else?

 

I wish i knew what it was

 

It doesn't look like cyano, but the red on the rocks does. Don't know what it is tho.

 

either algae or hydroids...what is the white on the tips? does it retract respond to stimuli etc...?

 

It does appear to be cyano. The oxygen bubbles give it away. See if you can siphon it off, if not accessible, use one dose of Red Slime Remover or Chemi-Clean. Reduce your feeding.
