Would Flatworm Exit kill Bristleworms and Eunicid Worms?

Was wondering if FWE is toxic to other species of worms and other creatures. Thanks!

I'd like to know the answer to this too. Previous posts have said that too high a dose will kill or damage many different critters but what about a low dose?

No. Even high doses won't harm polychaetes. Lots of dying flatworms can harm them though.
