Hi everyone. I'm new here and have a question. My 75g FOWLR
has been up for about 9 months and has a nice assortment of red,pink,purple and green coralline. In the last few months, I've noticed a rusty orange color algae appear. Hard and slow growing in very small patches. I know coralline can appear in orange but I've never seen it, even in pictures.
Anyone else have orange??
