My duncan coral colonies

Here's a few pics of my colonies. Not the best, but I thought I'd share.

Looks nice. I recently picked up a Duncan and it's being stubborn about opening up. Too much light possibly, even at the bottom. I'm gonna try feeding it tomorrow, see if that does the trick. It did open up a bit, but just barely. If anything gets too close, it pretty much closes right back up.

I'm curious about your setup - what are your alk, cal, and mag levels like? Are your nitrates in check? What type of lights are you using, and how high is the light fixture above the bottom of your tank? Also, do you have any fish that might be nipping at it - angels, butterflies, or rabbitfish, for example? It's been almost a week and it's still not opening up, something's gotta be off.

Love the pics of your colonies, vortex9. Just got a neon green duncan myself, really excited about it.

Appreciate the share, looks like your tank's doing well.

Thanks guys, appreciate the kind words, glad you like the tank

My tank's parameters are in check - 1.026 salinity, zero nitrates, nitrites, phosphates, and ammonia. Alkalinity's at 8.4, calcium's 425, and magnesium's 1580. I'm running Radion G3's at about 50% and they're 24" from the coral. Right now, it's just a pair of Clownfish, some crabs, and snails in the tank. My hammer coral's doing well and the torch is thriving too. Both the torch and the Duncan were picked up from flintix9t at the frag swap on Saturday, and the Duncan looked great at the swap.

I think it's either the flow is too strong or something's stressing it out. I had a similar issue with one of my large duncan colonies - it was closed for days and I was stumped. Then I spotted an emerald crab chillin' amongst the branches like it owned the place. And if my tang tries to graze on algae near my duncans, they'll stay closed for hours.
