In response to Morleyz thread, I thought it might be fun for the folks here to post photos of their hitchhikers in a single thread. People have been posting excellent pix of things that rode in with their live rock or sand, including some good ones over the past few days (nudge nudge). I'll start with some that I have collected over the past few years. So please join in and add your photos, even photos of the same species, and maybe this can become a reference for the "what is this on my live rock?" questions.
There are also mobile polychaetes, like this fireworm:

Some claim that bristleworms prey on things, but I haven't noticed any evidence of this in the years I have had them in my tanks.
