I have the "flat" snails pictured in the newsletter which mentions they are "harmless" but they can and do eat fish eggs! in many of my killifish tanks, i have lots of java moss for them to spawn in, and if the snails are there i don't get fry. I too crush them as food for my shrimp. dave _________________________________________________________________ Climb to the top of the charts!
