This is my 1st acro since getting back after 15yrs. I've had him in the spot in the picture for a couple of weeks from a place on a frag rack for a couple of weeks then to this brighter spot. Since I've had it he's only fluffed up a couple of times. I can tell he's getting thicker and growing but he don't look the same as when I got it. The corals that are around it are at least 3" away. The shots deceptive. Everything else in the tank open up and extend feeders. Is this any kind of normal? I have good lights and flow so I dunno. Parameters perfect and fairly stable except for a dip in phosphate and nitrate I'm bringing up slowly. But the look of this predates that.
