    Hey folks...we just picked this up a cpl days ago. It was sold to us as a dendro, but it hasn't opened up really during the day, but opens fully after lights out. Maybe still acclimating or could it be a SC? Photo was taken in middle of the night...turned lights on quick for photo-op.

    I am all for it being a sun coral.

    Any explanation why it doesn't open during day? Still fairly new so maybe that's it? I have it placed on bottom and trying to shield it from the light by a LR overhang.

    In nature, plankton usually floods the reef at night so corals, especially the non-photosynthetic variety, will only extend their polyps when they "smell" food in the water.

    Ahhh...I see. So regardless of placement, this addition may spend much of it's time closed up?

    Yep. Definitely a dendro. I would know, because we have both a dendro and a sun coral in our tank :lol: Well, we're trying a sun coral anyways. He's yet to open up at all though.

    You can sometimes "train" a dendro to open during the day. If you're lucky, your coral will "learn" that food comes in during the day. But ours only opens at feeding time and at night.
