Help needed with open brain Coral!

[stevepaynr84]

Ok so I bought my first open brain Coral today and now when looking at it in the tank it looks like something keeps coming out of it. I'll post some pics to show what I mean but they're not the best... do I need to be worried or is it all Cool

Looks like a coral barnacle. Shouldn't hurt the coral. I have a couple on a tenuis and no negative effects. That's a nice lobo, congrats.

Great stuff thank you! It is constantly popping in and out does that sound about right?
