Hows this sun coral look to you gentlemen? Just picked it up as a freebie from the LFS as they didnt feel like feeding it. Got some zoas as well, do they look like bam bam's to you?
Nice deal you got there, if you take really good care of them you may nurse them back to good health and growing. They are a bit beat up, but they are opening so you have the hard part taken care of. If you don't want to take care of the black ones I have a tank that can take care of them very well. I have an orange sun coral and just purchased 3 heads of Duncanopsammia axifuga, I love corals that respond to feeding.
Those look like orange bam bams to me, Just like the ones I have except mine morphed to a more reddish tone.
Well its looking dying. Just start spot feeding it, preferably daily, with phyto/cyclops/brine/mysis and it should recover. I would recommend using cyclops for nutrition and mysis for meaty foods, as they will need the meaty to recover lost tissue faster than only the small foods.
