Cyano??

I was playing around with the camera today and was able to capture a good shot top down of a piece of liverock in the back of the aquarium. As you can see it is becoming encrusted with coralline very nicely but also has a red algae on it which the coralline is slowly growing over top of. I reached down to see if it was cyano and it isnt exactly slimy I would describe it to be more of a velvety kind of feeling. Just moving water around down not dislodge it but if you press hard enough you can almost peel it off in a sheet that remains intact. Is this some sort of cyano it is a lower flow area in direct light or something else?

 

Cyano grows over the top of everything and basically nothing over it because it grows so quickly. The maroon is a type of coralline. There is yellow and orange like the maroon.

 

So that is another type of coralline?? I figured being softer and able to scrape it off would rule out coralline

 

I think it is or at least that is all I have ever heard it called. It does seem to act like coralline in light preference although I think it can stand a little bit stronger light. It grows best for me in areas that coralline does but only on the rocks and plastic. I have not had any grow on the glass.

 

Does it look like the picture? It to me just looks like cyano and Im worried Im just talking myself out of it actually being so because I dont want it lol

 

Yes it does, I have seen Emerald crabs eat it.

 

hmm only crabs I have are various hermits and then of course all the snails, they crawl on it but never seem to eat it.

well if its not cyano then I guess there really isnt a reason to be concerned about it. thanks again you seem to find all my post

 

I've had red coralline, and green too. The coolest was red and green striped.

+1 no worries!
