If it's exactly like Wolfen's then that's good! It's a type of coraline algae that I think is the most beautiful. It's deep, dark velvet red. It can look like cyano at first glance, but upon closer inspection, it's very low profile and encrusting on the rock. Cyano usually gets thick and gelatinous and can be blown off with a turkey baster.

From what I experienced, this type of coraline doesn't like a lot of light and tends to grow in shaded areas or on undersides. IMO, it's somewhat hard to please. It's the purple ones that are the easiest to keep. That's why all our tanks are purple, and not red. Too bad though. Coraline also comes in shades of white and green.
