Hi Everyone.
I have 2 LPS corals that have similar white squiggly stuff that comes out every once in a while. One is a Lobo (Below) and the other is a brain coral. Has only happened on the brain once but the lobo has it more often.
What does this mean? The lobo has small amounts coming out of three spots.
I figure it is either defense related or growth related.
Thanks!

It is a collection of mesenterial filaments. This is basically the corals digestive system that's being expelled due to a stress. Most often the stress is an attack from a nearby coral but it can also be caused by physical damage from crabs or something falling on it.
