Gulf live rock has been in my new 30 gal for about a month now. Just added the clean-up crew yesterday, and while I was righting the astraeas this morning, I noticed another, much faster moving, critter in the midsts. It was mostly hanging out in the nooks of the rock near the sandbed, occasionally cleaning bits of sand out of its adopted nook. I did my best to get some pictures when it came out to investigate the astraea. Thoughts? I will try and get better pictures if it comes out of hiding again.
