normal but keep an eye on it. if it appears to be folding itself inside out it could be dying. I've had one look great for 4-5 days after bringing it home then for some reason it litterally pushed its guts out the mouth and couldn't get itself righted again. I ended up having to remove it. Right now yours looks fine though, they are finicky things and some have trouble adjusting to new homes if the water isn't the same as the stores.
