normal fish behavior
I just purchased a coral beauty angel, yellow watchman and royal gramma. The angel swims around pretty erratically and kind of darts when I get close to the tank. He looks health otherwise. The gramma pretty much hangs around in the rock. He did come out when I fed them last night, but darted back in he got a piece of food. The goby and tiger pistol shrimp already teamed up and made a cave under the one rock and haven't seen them since. Is this normal behavior for these fish or should I be concerned.
