Can I operate on a starfish?

I have a red spiney reef safe starfish and it appears to have a injured arm. It seems as if it is hollwed out with no feelers except at the end. It just hangs in the water unlike the rest of the arms which are showing no signs of problems. The shrimp have started to pull at the infected arm. Since starfish can regrow arms I was thinking that I can take a sharp blade and remove the infected arm and hope for the best.

Just leave it be. Starfish sometimes loose their arms, they will regenerate.

Anways I cut the leg off underwater and he then continued about his business. If the shrimp starts with him then I will isolate him in a container.
Also I double posted by accident so refer to the other post as it has more respones.
