I was just wondering if anyone had experienced their Banggai Cardinal tapping the glass wall. Whenever I'm around the tank, I hear a tapping sound. Its not loud or anything but you can hear it enough if you actually listen. Now, the first thing I thought was either a mantis shrimp or pistol shrimp but all the rocks I've added were dry. Half was from BRS and the other half locally and it has been sitting dry for quite some time when I had it as well. So looked around and sure enough, I see my banggai cardinal tapping on the glass. I wasn't sure at first but everyday when I do my daily routine on my tank and when I observe my tank, the banggai would occasionally tap the glass and you can hear a tapping sound. Is this normal?
