Urchin and green hair Algae

[thall17]

My Urchin has a lot of green hair Algae on him....is that normal / ok? Don't they eat that?

My urchin would have an afro on him from time to time, haha. This is perfectly normal. While it is eating the algae on the rock, it is probably picking up some algae in the process (urchins have a tendency to carry things around the tank)

Same. Mine likes to wear bubble algae hats.
