I have a yellow birdsnest (panope I think) that is new to my tank (one week). One tip is totally white. The rest of the coral has the feeder tentacles on it and color in some areas, faded in others. There's also some new growth. Is this anything to worry about? Tank parameters are all normal. I think the stress of the new tank did it. Any thoughts? I'll take pics when the blue lights go out.
