Black spots on my clown

[dgobyfan]

Hello new to the forum and new to tanks.
Today when I was doing water changes I notice that my adult clown had black spots on him or her. Ahh is this something I should worry about? Hes eating and active I just never seen these spots before. He has been in my tank now for about 6 weeks. The tank has been around since 9/15 it is a 12 gal nano cube.
Also how bad are brittle worms?
Any sugestions I am a bit worried?
