Some type of .. I don't know

some type of mollusc-eating flatworm. Congratulations on getting it out! In the absence of molluscs they can either go a long time without eating or else they get by with other types of food.

thanks for the reply, at first I thought it was a mushroom floating around. It's about the size of a quarter. No mollusc in my tank...anymore

I am real curious to this. Weve talked about mine before, but ever since I found that first and huge fat one years ago I have had these things in my systems ever since, and while I no longer keep any clams, and very few snails, I keep finding more and more of them, and more frequently as of late even without any obvious food source. The few astrea I have seem to hold their numbers, but I have pulled out no less than 15 of these polyclads in the last 6 months. Granted, I have over a thousand gallons of reef, but it is all barebottom with little rock. I find them at night when the lights are out roaming, or every time I pull a rock out for any reason I give it a quick inspection in all the holes and I can sometimes catch a glimpse of them pouring themselves away down a hole.

I really wish I cold starve these things out and be done with them. All the ones I have been finding recently are no longer than 2" extended, and they do not look fat and or healthy by any means, but they still exist. What the heck else could they be eating Leslie??
