Does anyone know what this is in the picture below? It’s not cyano algae. I had cyano before and it does not glow in blue light the way this stuff does. Maybe a sponge of some type? I don’t know. Hoping someone with some experience can help me out here. Thank you guys and merry Xmas!
P.s. I had this stuff for a while now. Tank is about to be a year old in March.
