Hello everyone, recently my brother and I bought a pair of WC 2.5 year old true percs from a local reefer. They are healthy and eating fairly well. The question I have is concerning the branching hammer coral that they host. Now the hammer has about 25 heads and is quite large so they don't seem to be doing any damage to it, but I was wondering if it is normal for the female to just stay in the hammer all day in the same spot, only days ago she used to swim around the tank more and now she just hangs out in the hammer all day. She also swishes her tail in the sand some too. I was just wondering if these behaviors are normal or if they are a bad sign. I'm more concerned about her staying in the same spot (she still is swimming in that spot, not like the motionless clown thread) as I know that clowns often move sand and rocks around the tank as they please. Any help would be great. Thanks, Charlie
