Mushroom behavior curious if normal

[megatsea]

I have never seen my mushrooms do this. I placed some coral food in the tank, and it formed into a translucent bowl ...then reversed into a curling pattern....was afraid it melted over a shell ...then popped back into shape....
is this a normal reaction?

Mine do that from time to time. They seem happy and are still alive so "imo" i have to say this normal.

Actually, it was amazing...didn't last long but was a surprise...thanks for the reply.

mine usualy do that when i feed them, or when food lands on them i think they curl up to eat

that looks like basic feeding behavior. they cup to bring food to the mouth and to hide it from thieves like shrimps and fish.

My corallimorphs also close up like that when they get fed. I've also seen one of mine do that when my goby decided to lay partially on it. It made him move : )

This did not curl up as it usually does....it wrapped down tightly around the shell its attached to as if it melted...then curled up afterwards.....

correction...when I feed the tank now...it does exactly what everyone says as I watch it cup up. So cool
My yellow goby perches on it most of the day.
