Anybody who doesn't believe Cleaner Shrimp will eat healthy snails are sadly mistaken. I was constantly adding snails to my nano to replace the ones that left nothing but their empty shells. Because I was always told that these shrimp won't eat healthy snails, I was inclined to believe the snails weren't healthy. I even replaced a cleaner at one point because he got too big for my 14 bio. And still my snails continued to disappear eventually, even with the new cleaner. I got rid of this newest shrimp about 6 weeks ago and I haven't lost a snail since. Go figure
Another thing I was told is that Nassarius snails won't crawl out of tanks. I had 2 large Orange Spotted Nassarius snails. Now I have 1. 1 of these snails refused to stay in my 30gal. tank. Four times I found him on the floor. The last time he wasn't as fortunate. Apparently he was out too long. I kept his shell. That's all I had left of this $6 snail. So don't believe everything people tell you when it comes to SW aquariums. People can tell u they're own experiences but nobody knows everything about this hobby. (although some people believe they do)
