That looks awesome with the polyps retracted. It almost looks like cyphastrea.
Nice piece. Having seen retailers charge up to 25 a head, that must have been pricey. I had a 4 head dendro before my tank crashed from the hurricane, they grow new heads pretty quickly.
We need to see a pic wit it open
You would not believe how cheap it was.
Try cuttin ur flow off n covering it with food n see if they open up :eat:
Rook,
Grab some sort of Rubbermaid tub that will hold the entire colony, Place it underwater and place the colony inside - don't let it expose to air. Remove the tub with colony and water, Feed large amounts of phyto/mysis and allow to sit for 15 minutes, during the 15 minutes you can gently stir. When returning the piece you can allow to hit air or maneuver it where minimal water returns to the tank. Repeat until it opens over the course of a week. If it does not open after 2-3 attempts its probably in very bad shape.
Are you sure those aren't sun polyps THEY ARE VERY SIMILAR TO DENDROS ONLY THEY DON'T OPEN DURING THE DAY
