My Snails Have Stuff Growin on it.

[ryanbooton]

I bought these snails cause the looked old and had these things and moss growing on it. One looks like its got a live flower on it. It goes down when it gets scared and comes out like a flower when its not. Is it good or not? Will it spread to my tank?

Sounds like a fan worm...my hermit crab has one hitchhiking on his shell...they won't hurt anything...actually, they are good to have...

I have a dwarf crab with what seems like an extra shell on it's shell, thats opens up and looks like a feather duster comes out. No harm.
