Luvzz - Wow...nice find on a piece of rock! That's a "chalice" coral...usually worth a pretty penny depending on coloration. The second photo you posted is definitely bleached. You'll need to move it to a lower light area. It also has some cyanobacteria growing on it, so you'll need to regularly use a pipette/turkey baster to squirt it off. Since the coral has lost most of its photosynthetic algae (zooxanthallae), you'll need to feed it about 3x per week. In order to do that, you can turn off the flow in the aquarium (preferably after the lights have been out an hour), and drop a fish food pellet onto each mouth (the eye-looking spots that still have some color.) Within 30 minutes, the coral should extend tentacles and open its mouth to eat. If it doesn't, don't worry. Just remove the food and turn the flow back on and try again another night.
Wildman - Have you tried feeding the duncan? They can be pretty voracious eaters, so that might help speed it along. Nice on the scoly trade...but what's that coming out of its mouth?
SushiGirl - That poor thing! Has the worst luck, but at least it isn't giving up! Good job on all the saves!
