I recently upgraded my lighting and my corals are responding to it well. In particular, I've had this chalice for months and it looked fine but growth was minimal. In the last week, I've seen amazing growth and I keep seeing a reddish brown tube looking thin sticking ou of the edge of this coral. Also there is sometimes a thin string coming out of the tube waving in the current. Anyone know what this could be?
