I think you have a Sun Coral. I have both a Dendro and Sun Coral. Pics below. My Dendro is always open. My Sun Coral is only open when feeding time (or when it senses food nearby). If I feed my Sun Coral in the morning, it will often stay open for much of the day (wanting more, I guess).

The Dendro head is much bigger, too, and has longer tentacles.
