Coral ID please

[Just John]

After spending way, way too much time looking for this online, I think I know what it is. I think it is the Northern Star coral, which is a cup coral as several people suggested. It's range is from the Gulf of Mexico to way up the East Coast. It looks the same and comes in the same cream color as mine. Thanks for the help everyone!

It looks like some sort of azooxanthellate cup coral.

I have been spot feeding it, but It has a little green coloring under blues

They are transparent, but they do fluoresce, so I believe they do have zooxanthelle. The transparent coloration appears to be their ‘healthy’ coloration.

Azooxanthellate corals can flouresce too.

I also thought they had to have zooxanthellae to fluoresce, but I just found this from some research done in Japan:

"Corals have been expected to signal free-living zooxanthellae in seawater to increase the chance of meeting potential symbiotic partners, but we did not know what the signal was or even whether such a signal actually existed." said Associate Professor Shunichi Takahashi of the National Institute for Basic Biology in Japan. "We focused on the green fluorescence emitted by corals, and showed the first experimental evidence that corals attract free-living zooxanthellae by their green fluorescence produced by certain proteins in the coral."

It is neither

I'm out, good luck
