Tuxedo Urchin has Algae on him?

[demariners]

So I got a Tuxedo urchin and he is doing real well. However has Green hair algae on top of him and it is growing and growing. Should i be concerned and should I pick it off or something? Thanks.

He wants a wig!

Tuxedo's do this, they go around and pick up any rubble, coral, algae..

Basicly anything not glued and anchored down. Mine had troll hair 10 inches tall! I let it be for laughs!

Eventually the fox face gave him a hair cut..

They pick up hair algae. It won't hurt them, don't worry. If it starts to bother you, you can reach in there with some scissors and snip it down shorter, but I personally like it when they're just gathering things.
