Ricordia fell off

[pallidamors]

I have a piece of lr with about 9 ricordia mushrooms on it. I checked out the tank today and one has fallen off into the sand. What would cause this? Also on underside of some of the lr, there are these white sacks that are gowing, they look sort of like sacks. Anybody know what they might be?

It could have just let go to find more room.Or it might not have liked the flow where it was at. They will move around sometimes.

I have quite a few, every once in a while they seem to do that. As long as it looks healthy and is opening to feed... If it isn't stretching open in the light to feed then something is wrong. They should move/ wave in the flow but you don't want them pinned.

The white sacks without a picture...I guess harmless sponge
