Cyano or Coralline?

[Pflanman]

Hi I was just wondering if anyone can tell if this is cyano bacteria or corralline algae? Parameters are good. I tried to see if I could blast it off with a baster and it doesn't move. I havent introduced corraline to the tank other then it being on a few of my hermit crabs.

Cyano usually will dislodge quite easily with a turkey baster. Probably coralline.

I'd say coralline based off not coming off easy. I've had coralline the same color in tanks in the past.

That's great news, thank you!
