gws3 September 3, 2017 Share September 3, 2017 I saw this guy in some liverock I'm cooking a few months ago. Today I finally spotted him in a spot I could pull him out and take some pics. He's about 3" long, stretches to about 4" when he's on the move. Very responsive to light, he shrinks up quickly when I shine the flashlight on him. I'd like to ID him to verify he is reef safe and understand what he eats. Let me know if you have any idea what genus/species he is. Link to comment Share on other sites More sharing options...
gws3 September 3, 2017 Author Share September 3, 2017 I think it's a polyclad from what I see online. Eats snails / molluscs. I guess he's going down the drain. Link to comment Share on other sites More sharing options...

gws3 September 3, 2017 Author Share September 3, 2017 (edited) Thanks. Looks like they are a well known pest. Never encountered one in 10+ years of reefkeeping. I put him in freshwater and he started going nuts, expanded and disintegrated within a minute. I am going to dip the liverock in freshwater to kill any of his brothers. I feel bad killing them but my snails are much more valued. Edited September 3, 2017 by gws3 Link to comment Share on other sites More sharing options...
Squishie89 September 3, 2017 Share September 3, 2017 I had a polyclad problem. Luckily they were isolated in one rock. I used boiling freshwater and would squirt it in the holes where they lived, then catch most of the pieces that would fly out. It was a crazy few nights doing all that, but it worked.

menglish September 3, 2017 Share September 3, 2017 Definitely not reef safe. My wife spot one in my tank that was eating my snail. Get it (them) out if you see more. Link to comment Share on other sites More sharing options...
gws3 September 3, 2017 Author Share September 3, 2017 If I find another one I may do an experiment to see if they eat vermetid snails. I have a large variety of vermetid snails in my old system that is a huge nuisance. I could remove all the good snails and let the polyclad wipe them out and then let it starve. But first I need to put one in a container with some vermetids. Link to comment Share on other sites More sharing options...
