Actually I cant even begin to count how many crevices, nooks, caverns and caves are in my tank. I've got about 100 pounds of live rock in a 77 gallon tank. A couple things that have me worried is the longest any of my fish have been shy for is about a day (bi-colour blenny) and I'm also concerned he may not be getting food, that and theres a chance one of my fish may have taken his attempts to clean the wrong way
