I notice on my Sps failures these guys go in after the piece is done. Never see them on a piece when it's healthy. Are they just eating algae or are they f'n my Sps up?

Hermit crabs? If so they go in there to molt as they feel protected by the coral branches.

No not crabs they look like conchs that are tiny. Their "foot" is not like a snail more like a conch if that makes sense. But it could easily be some small snail. It hitch hiked somewhere along the road.

It doesn't have legs when it moves and I can see the slimy V looking foot it has.

look more like nassarius snails... They seem to hide until something dies and then they come out to eat it

The shell is white and they are pretty tiny like 3/4 the size of a dime. But I think your onto something because they also were tag teaming a dying acro a few months ago.

I had one of these before. Pretty funny because I had it for a long time and would only see it in rare occasion but on my acros. I put him in my sump for a while and i was doing some rearranging of my corals and some how got back in the DT weird. Well, to answer your question I think they eat sps or at least find a week one with damage and start to much on it. I have no proof but thats what I think. Even if its eating decayine acro I think it stress it out to where if the sps had a chance it will not make it because they are not giving it a chance to recover hth.
