What is this bright green coral?

[Onewolf]

I saw it at LFS in an invert tank. Mostly white with slight blue light yet this thing glows bright green. Sorry for my newbie ignorance, but What is it? Thanks.

It looks like kyptonite candy cane, a LPS coral.

Trumpet coral. Caulastraea sp.

And for clarification those are the exact same thing. This guy has a few names

Correct, trumpet and candy cane are one in the same. I just can't see a candy cane from a trumpet looking coral, so I call them trumpets.

Like others have said...it's a Trumpet/Candy Cane Coral. I have seen that neon green one called a Kryptonite as well as an Incredible Hulk Candy Cane. I have two of them and they react very well to feeding, (if you choose to feed them). Not sure how fast they grow since I have only had mine for a few months and they have not grown any additional heads yet, but when they get fed they swell up and get really fat for a day or two and they always have their feeder tentacles out day and night. I really like they way they seem to glow and plan on getting a couple more to spread out in my tank.
