I love Linckias. Around here and even online anything but blue is impossible to find. I'd pick up a red or orange in a heart beat. I've had my blue a couple years. He is pretty interesting to watch he can fold himself into any kind of position in crevices you would never think he'd fit in. I don't feed mine anything. I've actually never fed my stars, but my tank is relatively mature so I think they find stuff on their own. If you're picking up from your LFS and not having it shipped just make sure you slowly drip acclimate to the salinity of your tank. Stars do NOT respond well during acclimation even if you do everything right. It's a coin toss if it will do well, but as stated above make sure his skin is perfect. NO gashes or white spots. Another thing you can ask is for them to put the star upside down. A healthy star will try to right itself quickly a sick one won't. Keep us updated.
