Brain Coral?

[jeslynben10]

Anyone able to help me identify this bad boy?! I think it's a brain coral but unsure. Also I have noticed these thin, long tentacle-looking strings that come out of it at times. Is that normal? If so, are they dangerous to fish? My clownfish are not to fond of it lol

repost a pic under white or natural light. Colored lighting can change the perceived color of the corals making identification much harder.

the long skinny white tentacle things that come out at night are sweeper tentacles. They attack nearby corals and try to catch food. Make sure there is plenty of space around it and if any nearby corals start dying, move them.
