Bringing back this dead thread for some more insight from the more learned. At the beginning I bought a coral that was supposed to be montipora digitata. It was pink and bright but had no polyps...see below
As per the rest of this post and one at reefcentral with Eric Borneman, I never knew what this was. Mr. Borneman's opinion was that it was a dead coral skeleton that had been covered by a sponge and that it would die. Discussed here
Update: Over time the color did indeed fade and the entire thing died and became covered with corallines...or so I thought. Now the reason why I revive this thread. Below are recent pics of what I found when I decided to pull it up and discard...
And a close up view...
So now that I've discovered new growth and know that this isn't dead...again I put to you...What do you think it is and what are its requirements? Thanks for any help.
