something is eating my softies

[beginnermatt]

I have a pink finger leather and a green tree that is being attacked. I'm not sure if it is a fungus or most likely a parasite. It's many small black things that are eating tissue. Some are on the surface and others are in the tissue. The ones in the tissue looks like a splitter in ones finger. Any idea what this could be and how to stop it. I did sever the base once and it reappeared. Thanks in advance.

Ever watch the tank late at night? Leave lights off for a while, put in some food and turn on a red light and see what scatters. It may not be a pest but some worms and nudi will eat soft corals. Is anything else affected? Can you post a pic of the damage?
