Hello everyone...

I have a few zoas.. one of them was not opening, gave it a dip in seachem reef dip and put it in a QT.. that's when o noticed this... there are no others like it in the tank.. at least this is the only one I've spotted...

Need your help to know if this is good or bad...

Is it hard or squishy?

 

[ramasezz]

It's hard in the outside.. and it's shaped slightly spiral like.. and the opening is at one end of the spiral..
