Well yesterday I got home from work and was checking out some of the snails I got in my tank. one was sitting on my magnet cleaner so i got to get a really good look at him. I noticed that something was comming out of his shell, then going back in, then another one on his shell came out, then they both did. What the???? Could that be the snail? Maybe it is some sort of way that he feels to see what is around him??? I went to the lfs last night to pick up some fish when I asked what it could be. He told me that it is a feather duster and probably latched onto him at some point before I got him. What is a feather duster? I always thought that it was some sort of coral. If it is a coral, won't it die due to my "lack" of lighting strength? Do I need to feed it, and if so what do I feed it? Also, it is so small I tried to find the snail again this morning but of course he is mia, even if i did find the snail the feather dusters are so small that it is easily missable.
