I recently purchased a Starry Blenny and the first couple days he was swimming around. I noticed last night that I hadn't seen him at all, that evening. Today when I got home, I checked and didn't see him anywhere, I looked in one of the holes in my live rock and I think I found him. I'm worried that he may be stuck. There seems to be two holes, one looks smaller than a dime and the other maybe the size of a nickel. Should I assume everything is okay and wait it out, or is there something I can do?
