Can anyone identify this shrimp-like creature

[drumscott]

Hi, hopefully someone can identify this thing. It hitchhiked in on a live rock. Is it harmful or helpful?

Thanks!!!

54, he's got another thread going about the same question. New member with less than 15 days/posts, can't post pics yet. Tried to explain it on that thread.

Use of a site like photobucket can assist with the process of ID'ing your mystery critter.
