Need a couple of ID's. These popped up on the backside of a mushroom/zoa combo rock. The first I think is a spong of some sort. The second on looks kinda blasto'ish and has spread quickly from almost nothing in 2 different spots. This is from my Mom's tank 200 miles away, so all I've got is the pics from her gallery. Please give it your best shot and offer your opinion.
Fleshy growth the thumb is pointing at: Spong?
Blasto/acan/brain looking coral above the zoas?
