AEFW attack Birdnest?

[NatureNerd]

So I have been nursing this one piece of Green BN coral for weeks. All other corals look fine. This one lost its color and then started getting mid-branch tissue loss. Yesterday I found a dark brown 3mm sized critter on it. It looked slug-like. Could this be AEFW's? I thought they did not eat BN corals. Are there other predators that would look like this. It did not really look like the pictures posted in the pest thread and seemed too big. Perhaps it was something eating the dead tissue not causing the damage, just cleaning it up. Any help is appreciated.

"Dark Brown" leads me to think Red Planaria, which are harmless flatworms.

Thank you for responding but, I have see Red Planaria before in other's tanks. This was not at all redish, a shade darker than the browned-out coral, more of an undefined oval shape, without the "tail structure" of planaria. It was the right size though.

Do AEFW's even attack Birdnest corals? I don't think so but I haven't found any confirmation.

there seems to be many differnt kinds of acro eating flatworms- some say they would only attack tri colors while others have ones that affect only there millies. could possibly be them- if you cant take it out and dip it if more fall off it probably is or take a turkey baster at night with a flash light and blow away.

I tossed the colony. It had been struggling for a long time and had lots of damage. Before I did, I tried to blast anything else off it and found nothing.

I just hope the rest of my SPS aren't going to start showing damage.
