Hey! We've had a coral beauty for about a week. He's eating and looks healthy, but he spends almost all his time in back of tank. He comes out when he thinks no ones around but as soon as I approach the tank he zips back behind the rocks. Any way to get him to come out more? I only have a True Percula and a black Percula in there with coral. So I know he's not being harassed. Any suggestions?
